Title: Nebulae
Post by: Denis Sirenko on July 26, 2017, 07:40:59 AM
Hi all!

I decided to create a new topic for nebulae. I plan to publish nebulae here as they are created. And let this be the first. Terragen + Photoshop. Here we have two of several dozen nebulae that will be in the game.

Nebulaes do look easy to make in theory.
But to make a nice one is not always so easy for me.

Yeah, that's definitely so. It would seem that these are just clouds, illuminated by stars. But there are many subtleties on which everything depends. Fortunately, I have the opportunity not to repeat exactly the real nebula. I'm more inclined to some artistry.

Yes, new colors have been added. But the main colors gave me Terragen. These nebulae gave out 4 shades of color, although they may not be noticeable. But in Photoshop they are easy to amplify. I also added a few other low-visibility nebulae, and I corrected some unfortunate places of morphology a little. In the future, I want to reduce this work to a minimum.
Title: Re: Nebulae
Post by: Dune on July 28, 2017, 09:05:02 AM
They look awesome. What I actually meant was if they were cloudbased (TG) or power fractal based (TG), or actual (flat) maps from PS...
I guess with the new smoothing shader cool cloudshapes and/or mixed with partially smoothed PF's on the BG can be made, and used as nebulae.
Title: Re: Nebulae
Post by: Denis Sirenko on July 31, 2017, 06:38:25 AM
Oh, I see. Well, I did not use anything from Photoshop for generating forms. It's just Cloud layers, Cloud and power fractal shaders and warpers. Yes, I really want to try new smoothing-filters. While there was no time for it.

I'm impressed even more now. So, do you put your cloud layers way up in the 'galaxy', far from the main planet, or closer by? In the first case you'd probably need very high clouds.

Stormlord, good result. Nice color combination and a beautiful thin blue layer. Although I would customize a little more small details. Also good distribution of small, medium and large stars. It is difficult for me to achieve this. And where did you get these stars? Is it the Terragen?

And here I have another new nebula. It is called Tolibro.
Title: Re: Nebulae
Post by: Denis Sirenko on August 15, 2017, 05:09:05 AM
By the way, Stormlord, try to increase cloud depth. The nebula will become more complicated and interesting. The upper limit is about 1000 km. But the render time rises rapidly. It is desirable that all Cloud layers have one cloud depth, although here you can experiment.

Thank you Dennis for your tip  to increase cloud depth... I'll try that.
Last night I rendered another spectacular nebula, based upon your modified TGC File. It's another one in the same style, but quite a little bit diffenrent.
I the next future I will try to find out some other good colour combinations.

The stars in my picture has been created in 3D Studiomax, not in Terragen. It's a simple Omnilight with a Lensflare effect. So I rendered some different sizes and effects (star, glow, lens-flare, strikes) and created a master star chart for personal use. This Starchart is handmade and can be seen in the Photoshop Screenshot attached. I aslo used another handmade starchart with a tileable star map. I just fill a layer with them and apply them with negative multiplication over the whole picture/nebula rendering. Finally I also have a sharp and big astrophoto only with stars and galaxies. The second picture shows a composite from the rendered orion style nebula and the real astrophoto.

A very good resource to cut out stars or nebulas is ESO. Here you will find good pictures and realy excellent astro photos.
http://www.eso.org/public/images/viewall/

So let me ask you Dennis...How do you make your stars? Do you just paint them?

Title: Re: Nebulae
Post by: Stormlord on August 18, 2017, 07:44:16 AM
@ Dennis....
Before I answer your questions I have one for you Dennis. How do you make these faint small tiny details (the black dust structures) in your picture "Hulakara-Minkares nebula" ? I can't figure that out..., how do you make them? Do you render them in Terragen (so is it just a question of settings) or do you stamp them later on into the rendering via Photoshop? Hmmmhhh....

Well...thank you Dennis for your quick response!
I know Hubble and to get the colors just from HST Galery is a good idea. I used a nice astropicture from ESA of the Orion Nebula M42 which I had in mind in my first attempt to render a nice orion-styled nebula. I just found the colors composition by chance, using the trial and error method. But it worked perfectly, the result looks very convincing...

If you like to render your own stars in3DsMax, I could send you my Max-File. It is made in 3dsMax 2009. If you have the program, you could use my setup to render your own stars in a big resolution and excellent quality. This would provide you also the Alpha Channel, so you will be ready for masking. Just mail me, I can send you my file if you like... :-)

I use the negative multiply method for fading stars into a picture or to overlay a scene. Just lay the stars layer over your rendered space scene (nebula) and apply the negative multiply blending method for your star layer. -> Good for fading stars into an evening sky! I rendered a big Master Star in 3DsMax over a black background. In different smaller sizes I created my master starchart. So I just need to copy them into my scenery with the negative multiplication blending method. In the result, everything which is black becomes transparent and so you just got your star hovering in free space and can put them in the right place. As an example please look at my picture "013 Luz del Mondo" or "004 Morgenrot in Alaska" which you can find here... http://www.dirkkipper.de/Galerie_Terragen/Terragen_01/index.php

Thank you also for the Link with the NASA Starcharts, I already got them. I have created additionally all kind different star maps to use them in my own animations. Also own star maps for special purposes. I created one, based upon the NASA Starcharts only with the bright stars of the constellations for instance. So I'm able to fade over between the milky way and the constellations and their main stars only. I underline them with my favorite music just for viewing and relaxation. They're excellent for a cool power nap. Hehhehehe.... Here is an example (the second video on the right side). Please notice the fading in the video... http://www.dirkkipper.de/Galerie_Video_Tutorial/Video_Tutorial_01/index.html#

I'll attach some pictures for your benefit to make it crystal clear to you Dennis :-)

Well Done!
I have been wondering how one would assign such masks in Terragen to a population of a single star object. There seems to be no way at the moment to assign a single value for each star dot in the mask. (Meaning you might get a cluster instead of a single star)
Rendering your clouds then layering post render would certainly be faster and leaves you with many more options for sure.

You guessed it, I make them a separate pass in Terragen, then I impose either the nebula itself or its alpha channel. It is also not bad to create a weak light nebula between the main nebula and the dark nebula. It creates a good air perspective for the main nebula and complicates the structure and appearance. A weak light nebula you can also render separately. I could do all this in one *.tgd scene, but I'm afraid that my computer will just explode. And since I know the photoshop there's just no point in this.

Unfortunately, I do not have time to study everything you wrote today. But I see that very interesting information. As soon as I can, I'll study. Thank you very much!

It would be wonderful, I would have studied more carefully. I'm not sure that I will need the alpha channel, since I put the stars through the ADD, but still I can see.

I understood. In the picture I saw that you have it called Negativ Multiplizieren. The fact is that in my English-language version of Photoshop this mode is called Screen. But I still usually use Add blending mode.

I generally did not find a way to make a large number of stars in TG. More precisely, I found one way, and he gave me a pretty good starfield. Here is the result:

Yes Dennis, I added some dust and dark zones into my latest space scene.
Here it comes... I called it Supernova Remnant and this time I used nice end summer colors (orange-red-brownish).

Some Alpha channels from other nebula renderings are subtracted and one is multiplied in this picture (I masked one alpha channel from a nebula with mask extensis pro to try this method). As before, I added some rendered stars in different colors and sizes and blended it with stars from a real astrophoto...

Theres also one screenshot from Photoshop attached.

As promised I can send you my 3dsmax files, but you must send me your e-mail adress via personal mail.

Dirk, try to take into account the fact that the nebula itself is not always transparent to the stars that are behind it. The nebula will become more tangible. That is, you can use the same nebula as a mask, but corrected by the curves.

But some stars are still piercing. This problem was solved by dividing the star field into two or more layers. For example one layer in front of the nebula, the other behind it.

Thx Dennis, this i really a good idea for improvement! I tried that out in this image, it looks more realistic and gets more a 3D depth, very good idea!

By the way... I have only an old Pentium 4 Quadcore with 2.66 MHz, rendering is still a pain for me. One big rendering takes around 20 Hours for me.

I'm constantly experimenting with my network of nodes. And some multilayered nebulae can take more than 100 hours on my Intel Core i5-4440 3.1 GHz (RAM 16GB). And this is without the upper dark nebulae. By experience, I can say that the rendering time depends primarily on the Cloud depth (100 min - 500 max), number of light sources (1 min - 7 max), number of Cloud layers (3 min - 8 max), and probably Cloud density (0,02 min - 5 max). Well, the rendering time depends, of course, on the quality settings. I usually use micropoly detail 1 and AA 5-7 with Defer atmo and Ray-marching quality = 1 (on Quality tab of Cloud layer node).
Title: Re: Nebulae
Post by: Denis Sirenko on August 29, 2017, 07:23:57 AM
Dirk, by the way, and over the nebula, small stars are still needed. Some of them are very bright behind the nebula, and some of them are closer than the nebula itself, but more dim. In general, the number of stars over nebula can vary, but they are, although there are fewer than in open space. I'm not talking about big stars, they're fine.
Title: Re: Nebulae
Post by: Dune on August 30, 2017, 02:58:56 AM
I wonder if such high detail level is necessary with mainly clouds, you could try detail of 0.1 and see if that's faster and as good.
Title: Re: Nebulae
Post by: Denis Sirenko on August 30, 2017, 06:43:12 AM
Dune, I think I've tried everything. I sometimes do not even have such settings, especially if the light source shines through a thin nebula. Here you can see the noise around the star. As far as I remember, this noise depends on both AA and Micropoly detail settings.

Although, of course, I might be missing something.
Title: Re: Nebulae
Post by: Dune on August 30, 2017, 10:38:29 AM
With these settings it's quite logical you get grain; AA5 is not very high, especially without defer atmo. If you try this with defer atmo on, mp detail 0.1 (my guess that would work) and AA minimum of 6, maybe 8, you probably loose the grain.

Micropoly Detail has essentially no effect on cloud and atmosphere quality when Defer Atmo is enabled. Set it to 0.1 if you don't have any non-atmosphere/cloud elements in your scene (as it seems is the case in these).

Sometimes I set AA=7 and switch on Defer atmo if I expect noise. Below in the picture you can see how little noise with AA = 7. But for so long!

Dune, Oshyan... you made me do some experiment. I made two renderings. One with MP details 0.1 and the other with MP details 0.1. Other settings: AA=7 and Defer atmo = on.

[attach=1]

There is no difference. That is expected, since there are no objects, the processing of which takes resources and time. So I'm still not sure if I need to reduce MP details. All the same does not work. And I was wrong about the fact that the noise depends on the Micropoly detail.

Great thing! Although it seems to me now that there are too many stars, but it is a matter of taste.
And one more thing. If we see a star occupying more than 1 pixel, then its middle should be white.

[attach=2]

The stars themselves are very small for us, and we see only their glare (except the Sun). And if something hinders the star, for example the nebula, then circle of the star becomes smaller and we see glare, but not a gray circle of the same diameter. And if the star was 1 pixel in size, then its middle becomes gray (or gets color), and the glayer decreases. Or the star hides completely.

If there is no terrain/planet, then it's not surprising that decreasing micropoly detail has little or no effect. But it's important to know you don't need high settings and that in fact, with Defer Atmo, the Micropoly Detail has no real effect on quality.

The new nebula is ready! It's called Gelfon-Esto.

All the nebulae rendered in Terragen. Stars and composition - Photoshop.
There are 4 clouds (two yellow on the left and two blue on the right) that I rendered separately. Total time of render is about 85 hours. And also many pieces of old clouds for dark and light thin layers in the foreground.

Excellent nebula, but the render times... 85 hours in total!
You mention 2 clouds left and 2 clouds on the right side, how many lights you have put into the scenes?

Nevertheless, the shape, colors and dustlanes are well done, this is a very good rendering of a space nebula and the compistion is Poposhop is great.
The only thing that I miss are some bigger stars in the foreground (maybe with glow or streaks) to bring ito the picture a better 3D Effect. So it is more a flat impression.

No, the full picture has a size 2048x2048 pixels. But since I do not know how big the nebula will be on a specific background (or maybe there's more than one nebulae), I'll render the nebula with a margin in size. So I rendered all nebulae in the size of 2048x2048 pixels too.

In addition, most of the blue nebulae are behind the frame and will be visible on a different background. Therefore, everything is not so scary :)

The new version of Terragen (starting with version 4.1.11) has already reduced the rendering time by 26-27%. I am very glad for this. But since I work a lot in Photoshop, the Terragen is not a bottleneck. I work on my computer, and Terragen renders on others. So there is no urgent need for us. It would be nice, but there is no urgent need.

2 clouds left - 3 and 5 lights. 2 clouds right - 3 and 3 lights. In fact, only half of them got into the scene. I'm a little spendthrift :)

Thanks for the critical comment, Dirk! There is nothing more useful than criticism, really. The larger stars we will have in the game, in the foreground, on a separate layer. They will be slightly displaced when the camera moves. So they will not only be, but will also be mobile! Perhaps, indeed, for an independent picture I need to add them. I did not think about it, thank you!

It's terrible to imagine the render time if you put it all in one scene. Even if only the brightest stars are left (about 10). 8 nested clouds in each other (four cloud nodes for each nebula), AA7 with defer atmo, more or less normal resolution... Ultimately, everything depends on hardware.

Yes, now it all consists of several layers in Photoshop. But they can be moved a little, doing something like a small animation in Photoshop, a little animated picture. For example, jets flickering, changing the brightness of the nucleus, a small displacement of near layers relative to distant, swirling thin layers and so on. But of course the full animation in the Terragen (for example a flight around) I can not do, the rendering this in one scene will take forever.

Indeed the big stars are from real Hubble photos.

By the time I found some big and pretty stars. But it's hard to find good looking and also big stars in a Hubble photo.
Further the stars must be in a surrounding, where you are able to mask them properly. Hard to find such...
Smaller ones are easy to find, but pretty big ones which are capable to mask them, these are hard to find and rare!

Regarding my picture "The Bridge"
I intended to make it more 3D, the dust lanes are great to improve the 3D Look and feel effect.

Yes, it is not easy to find an independent large individual star in good quality, without surrounding small stars. In addition, the Hubble stars are different from the others, they have four rays and typical just for him glare.

It is interesting that the place where the middle large star is located, and in front of it is a dark dust cloud. If there are such large rays, then there must be a bright glow, which obscures the dark cloud. That is, I think, if this star is put on top - it will become more realistic.

Hello all! I continue my generative-drawing activity.

This nebula is called Telegly. I tried to show a supernova explosion. In general, I'm satisfied. Although effect of motion from the point of explosion is still a problem for me. Stretching along one of the directions does not give a good result. The clouds look artificially stretched. Not bursting from the explosion. Therefore, I prefer not to do this at all.

This is a good job! I correctly understood that your illustration now uses the stars that you got from the photos below?

In the photo of Fomalhaut I really like the distribution of large, medium and small stars around Fomalhaut (starfield). But I still do not like the glare around Fomalhaut. It still seems too clouded to me. Because we do not see such a radiance around the Sun on the images with the ISS. And the Sun is a typical star.

And, Dirk, I still insist that the light around the star is an optical effect, not part of the star itself. This means that in the illustration, dark nebulae should be as if behind a star, although in fact they are in front of it. The irony is that the image of the star on the photographic images of cosmic telescopes we see so radiant only because of the imperfection of the receiver of light. The real image of a star is an infinitesimal point, so small that if it were not for this scatter on the receiver, we would not have seen it at all.

As far as I know, what we see from the sun is only the core. The glow around... this fine and faint glow which you can see in the evening belongs all to our sun! So the glow is part of our sun or stars. But nevertheless, In Astrophotos we usually don't see this faint glow around other stars. The glow in my picture above locks impressive and this is the reason why I put them into it.

By the way, I incorrectly said: "The real image of a star is an infinitesimal point, so small that if it were not for this scatter on the receiver, we would not have seen it at all." In fact, the pixel will shine, but only one pixel, which opposite the star.

I think it's easier to show what I mean. The left picture below shows how you realize the obscuration of the dark nebula. And in the right picture I showed how it really should happen on astrophoto. Even if the dark nebula is closer than the star. The star is further away, but the glare is closer. The glare is created by the camera lens. It's just light scattered by the optical elements of the lens. The  core of the star is very, very small. Less than the pixel size of the photosensitive matrix. For the demonstration, I used your wonderful picture of Fomalhaut.

[attachimg=1]

On the left you can see that the dark nebula is blocking the star's radiance. It's as if the sun was completely blocked by the horizon at sunset (оn the right is the original correct the setting sun picture).

I picked 70 years because before that we relied on earth's telescopes mostly for astronomical observation. Man reached further for the stars and got there. All technology, especially photography, has enlightened us with color and scale. Now we can imitate, in many media forms, with reasonable accuracy what the dreamers imagined. I have lived long enough to see most of this occur, so with comparison of historical theory and now fact, it is truly amazing!

So...that would be not share at all then? Are these for a client or something, or are you selling them and don't want to devalue them by also sharing with friends? Just curious. When you posted ": share with the watermarks or not share at all." it just didn't make sense to me.

Hannes, did not see Krakatoa simulation before. Right now just looked, looks cool, thanks for the information. I'm glad that something like real physical streams has turned out. Here I have three different cloud layers, which differ slightly in optical properties. But I'm still sure that Terragen can do much more. As far as I understand, in principle, Terragen can do almost anything, because it's just math. And mathematics can do anything :) It seems to me, that the question is more in the time resources for design and rendering.

And still there is a lot of work. This weekend I rendered several new pictures ... but it seems to have gotten a little worse. Tomorrow I'll take a closer look. If something is worthwhile, I will publish it.

Guys, I have a problem. A simple scheme, warp one fractal through another.

[attachimg=1]

And I sometimes see too active vertical elements and I never see anything similar in the horizontal direction.

[attach=2]

The camera looks sideways, that is, the Y axis is directed vertically. I tried to switch on/ff and adjust the power of various parameters of PFSv3. I can not understand where the problem is. Is the warper not able to correctly warp in all three axes? I tried all day to solve it, I could not. Maybe someone already decided this?

Duplicate it here, both ways work for me:

Quote from: j meyer on March 05, 2018, 02:59:57 PM
Don't know if it is a solution for your problem, but I would try to put a Vector Displacement Shader
between the Power Fractal(Warper) and the Warp Input Shader.
At least it allows control of the 3 axes.

Quote from: Matt on March 05, 2018, 03:22:18 PM
Warp is based on the displacement generated by the warper. Displacement usually happens in only one direction, which by default is vertical.

To create displacement along all 3 axes you can use the Redirect Shader and plug 3 displacement shaders into its X, Y and Z inputs. Alternatively, as J Meyer mentioned you can use a Vector Displacement Shader instead. This will do a similar thing but there's a very important difference. Vector Displacment Shader takes colour or scalar inputs (which can be the colour output from a fractal) and converts them to displacement, whereas the Redirect Shader takes displacement inputs and simply changes their direction. A Power Fractal can output both displacement and colour but be aware of the difference because they can look different and have different settings in the fractal.

You probably want to give different seeds to each of the 3 fractals. If you don't, you'll just produce a displacement that goes along a diagonal vector, not much more interesting than what you have now.

There was one attempt, but it was matte paint with NASA photos. But it quickly became clear that this was not the job I was dreaming about. Although with TG a satisfactory result is also not easy to get (if your apartment does not have a separate room for a supercomputer). In any case, it's good if it helps.

I'm assuming render times are not the best? With clouds quality really is a factor, me being on the free version I'm not sure how I feel about tackling this. I gave a couple attempts but my hesitation in quality did not make me feel confident in spending money on it... even though it'd probably be under a dollar on current rates but I I'm so strapped for cash it's not even funny.
Title: Re: Nebulae
Post by: Denis Sirenko on March 10, 2018, 05:16:31 AM
Now the final render time is much less than I wrote for all the nebulae that have already published here. The render time I was able to reduce almost 10 times, and with this improve the quality of the picture (almost fully removed the fine noise). That I rendered 60 hours, now I can render for 8 hours on the same computer. So this is not the worst thing. You just need to leave the computer turned on for the night and the picture is ready in the morning.

Much worse is how the settings are configured when the entire node network is connected and you need to see the result of a small adjustment of one parameter. As a result, you have to switch to an outlined node scheme or create test scenes and study the result after a few hours of rendering. Or you have to choose a small area (crop) and focus on it, but there is a possibility that the same parameter can have unpredictable influence on other sites that you have not looked at. Or it is simply good to know what and how it works and to foresee the result. The main thing for me now is precisely this.

As for the quality of the render on the free version. Is it different from the paid version? Judging by what is listed on this page http://planetside.co.uk/terragen-product-comparison/, the free version contains the same render-engine as the paid versions, and the differences are only in separate functional blocks, which are usually required for solid professional work with integration with other applications.

The free version is limited to 0.6 micropolygon levels, and 0.6 anti-aliasing. This has a huge impact on atmosphere/clouds. Which is entirely understandable. I played around a bit last night and have something starting. Still making adjustments with a small preview but even then the noticeable loss in quality is a little puzzling for small details, have no clue how they will look full resolution. Still worth every moment of experimentation and knowledge.

As long as you're using Defer Atmo, AA 6 should be enough to get low noise in most cases. At the least certainly if you use Max Samples (non-adaptive). Remember you can always increase the cloud quality, even if you can't increase AA. Also if you're using v3 cloud layers, take a look at the newer Voxel Scattering Quality setting in the GI in Clouds tab of the Render GI Settings node. You can increase that when you've hit a ceiling on quality from AA.

The fountains of knowledge that spring up around here. I'll tel ya. Thanks Oshyan, that's news to me, about cloud quality and AA limitations and also GI controls in v3 clouds. Going to try doing some testing tonight and leave one running tonight overnight.

Last planet I did with global clouds I gave up on. Mainly cause wasn't totally satisfied with the clouds in general, but boy, I spent two nights and half the planet rendered, while the planet itself can render at max TG (free) settings in less than an hour x.x LOL You can tell I don't Cloud well. Still learning all these optimization tricks.
Title: Re: Nebulae
Post by: Denis Sirenko on March 13, 2018, 04:33:28 AM
Maybe Oshyan will correct me, but it is not even necessary to use non-adaptive max samples. It is enough to put, for example, 1/64 first samples for First sampling level, and adjust the noise level with the Pixel noise threshold parameter (which is near). Most likely it can be reduced, for example, to 0.03-0.02. It has a very strong effect on rendering time, but it can completely eliminate noise.

...Also if you're using v3 cloud layers, take a look at the newer Voxel Scattering Quality setting in the GI in Clouds tab of the Render GI Settings node...

Does the increase in this parameter always increase the render time? For some reason, in my test scene (two nested a few different cloud layers v3 without any geometric objects) once I got the opposite result - the rendering time decreased when changing the value from 25 to 50 (by 13%). But at the same time, I did not find noise reduction at all. Perhaps I've already sufficiently reduced it in other ways.

Quote from: WASasquatch on March 10, 2018, 06:44:20 PM

WASasquatch, there is another way to reduce noise, use Photoshop's AA :). It is enough to render image a larger size than necessary, and then make the rescale down in the PS with suitable resampling settings. True, if the resolution of 1280 × 900 is too small for this, you will have to do several renderings. (About denoisers like Neat Image for PS, I do not need to write, I think -  such advice can offend  :))
Title: Re: Nebulae
Post by: Oshyan on March 13, 2018, 05:39:38 PM
I mainly suggested non-adaptive just so he can be sure that he is getting the most number of samples for a given AA level, i.e. the highest quality. This avoids having to spend time fine-tuning the noise threshold.

The increase in voxel scattering quality does not always increase render time, no. There are also other sources of noise which it might not have any effect on.

Title: Re: Nebulae

Will have to five the the methods a try at the very least. I know noise reduction in Photoshop is possible, but it can reduce fine detail if you're trying to remove a fair amount of noise.

It seemed amusing to me that sometimes increasing this parameter can REDUCE the rendering time. Although I admit that I could make a mistake in the optimization test itself.

No, the jellyfish was not yet, can be another seed needed :) In general, I do not need it yet. For jellyfish need a more crafty warper.

All this is absolutely exactly. But the fact is that the Hubble, by sampling his measurements, does this in different wavelength ranges, and gets slightly different grayscale images. The pattern of each of these measurements is determined by the chemical composition of the nebula and the physical processes. Then you just convert these different components in the colors, and you get natural color variations based on natural processes and differences. In my case, there is no attribute by which I can get different grayscale renders.

good job, me personally doing this job on terragen takes a lot of time especially the render . I prefer doing this work on after effects it's faster. but I respect enormously what you do.

That specifically is a colour image by a DSLR camera through  normal telescope here on earth. It was shot in colour, and composite programing used to exaggerate exposure and colours.  When trying to get a picture of lets say, Jupiter, to get it's colours, you need specific settings to get those colours. But lets say you wanted the moons in the shot. you need a super exposed image to bring out the moons...

I thought you were talking about jellyfish-similar explosions, such as nuclear:

As far as animating, I actually made a shockwave object from a torus in Blender a while back. I think an object might render faster than the clouds, I shall have to dig that up. That would give you a way to do a flight path, I think.

I'm afraid that then I will have to part with the softness of the edges. Although, of course, everything depends on the subtleties. And there are examples of how your result looks like?

The drawback of this scene maked in FumeFX (as well as After Effect), it seems to me, is that there are no shading (in the original sense). In fact, all the effects that I saw are glow effects, only lighting. But in nebulae there are also so dense clots of gas and dust that they hold back the light, completely stopping the movement of the rays of light. Here you need a real ray tracing or similar technology. And this, of course, is not fast. But it seems to me can make FumeFX, it's very powerful soft, although by your example I did not see it. An example of shading can be seen here: https://www.youtube.com/watch?v=ZJ7LbYBOntw

It was shot in colour, and composite programing used to exaggerate exposure and colours.  When trying to get a picture of lets say, Jupiter, to get it's colours, you need specific settings to get those colours.

The fact that we need to do some special settings to catch the colors of Jupiter because the image of another planet is in itself a nontrivial task. This is not due to the fact that the colors on the Jupiter were not at all and the settings can help created colorsfrom scratch. However, if you do everything right, then catch the colors that Jupiter has provided to you. The law by which these colors Jupiter appropriated, was already created, before you take a picture. In TG, however, to create colors, you must first create this law yourself and then start from it painting. I just wanted to say this :)

The jellyfish nebula as I understand it resembles an exploding cloud. A long time TG forum member has a few interesting clip files including an exploding cloud. I do believe Dennis's nuclear examples resemble such. As far as I can tell, Dennis is making his nebulae by warping clouds. I was simply trying to engage conversation about different methods, techniques, and cloud variety. Once again, I have probably overstepped.

Started playing around with the scene you originally shared. While doing so I accidently plugged in the wrong nodes to a warp and surface layer (meant for a mask) and created a very interesting motion effect. Refined it down to three nodes and re-rendered and got this.

I just used piped in my cloud into a merge shader, with the A Input scaled to 0.9 - 0.9 - 0.9, and than another warp shader warped by the master warper already applied to the original shape that was duplicated and scaled and merged.

I'm still trying to figure out how you do those fine rough details in the cloud forms, and the large twists without creating flat looking swirls with warp.

Added a recent test render... (these take anywhere from 10-30 minutes to render, not sure what creates the varying times between seeds and minor adjustments. I guess cloud mixing)

That's what I've wanted to do, but so far, unfortunately, lighting is very manual, and does in fact take time to get the "right positions" and sometimes you end up changing good things (in my case). I'd love a way to procedurally add light sources. Doing them manually to the point you have a star system may not be poss--wait... the PF star background... How did I forget? That would at least get your ambient stars out of the way.

Note: The PF background idea will not work without illumination on the background. I'm sure this could be done with a huuge spotlight but I haven't attempted.

Nacer, on the one hand, I see that the animation was created quickly and looks complicated. On the other hand, I can understand what mechanisms here were used without the use of 3D-technologies, only due to 2D-technologies. As far as I understand the ideology of After Effects - in the first place it is a 2D program, in which there are no serious possibilities for working with volumetric light. As imitation of 3D phenomena and processes is an excellent option and can be used for many tasks. However, I would like to get the most reliable image, with a real play of light and shadow on the volumes, taking into account the re-reflections, changing the lighting passing through the thickness of particles and so on. I still do not see an opportunity to achieve my goals with After Effects, because I do not have a goal to get a video, but I need a static and quite realistic picture.

The nebula is not as chaotic and complex as you pictured. It contains not only radiating components, but also absorbing, reflecting, and even re-re-re-reflecting (astronomers are now developing a technology that will allow to reconstruct the events that took place 10, 100, 1000... of years along the paths of light rays that are reflected in different parts of the nebula backward). The nebula can be seen as a landscape in 3D. There is no bottom or top, but there is a land, sky, trees and Sun. Many Suns! Look, what a beauty:

Carina nebula:

[attachimg=1]

NGC 6357:

[attachimg=2]

Orion nebula:

[attachimg=3]

After effects can not construct the nebula from its components, keep the dependencies between them when switching the seeds and rotate the camera 180 degrees and look from the back while preserving the entire structure. This is the territory of 3D-graphics.

But After Effects is faster and more artistic than TG can do animation of some processes, and also add some good effects. With this I will not argue. But in my opinion, it is better to consider it as an addition to TG, and not as an alternative.

Title: Re: Nebulae
Post by: Oshyan on April 06, 2018, 06:12:14 PM
Denis, I was referring to methods like After Effects, and other software that produces faster but poorer-looking results. As you yourself explained very well, they are not doing true volumetric (3D) calculations, shadows, etc. Realistic effects are much more time-consuming to create (from a rendering perspective, if not a creative/editing perspective). This is true even with proper, volumetric cloud simulation. It can take days to calculate a complex fluid simulation of something like a high detail volcanic plume, and then days more to render it with realistic volumetric light interaction in an animation. These are just complex problems.

I think your methods are very good for producing the realistic and beautiful results that you are aiming for. Some people don't seem as interested in realism or aesthetic, just in the fastest way to visualize an idea, and I guess that's valid too, for some purposes. But I for one appreciate realism and the beauty of these images you're creating. In fact, although I had seen some nebula in Terragen before which I considered to be realistic, you have "raised the bar" and shown me even more amazing nebula than I thought possible in Terragen. If it was something we could do in a single rendering pass, without Photoshop, I would want to animate it. :)

An interesting effect. However, with close study it is clear that the nebula is double. For me, this can be a problem :) But in some cases, for example, when the details of the nebula do not have clear boundaries, this may well be useful.

In fact, I have an unresolved problem related to the imitation of the movement of the nebula due to the explosion: at me with equal speed, both the rarefied and dense parts of the nebula are scattered. Look at this photo of a crab nebula:

[attachimg=1]

[attachimg=2]

It is clearly seen that dense clumps scatter with a lag, slower than more sparse areas. Thus, a long tail is propagated along the direction of propagation of the shock wave. So far I have not achieved this effect.

I'm not sure I understand the question. On the attached picture there is an example of "flat looking swirls", of which you speak?
Just in case, I will say that I use different warpers with different settings for large, medium and small scales. Therefore, the results of their work are not interrelated. And now I'm working in a completely new scene, and not in the scene that I posted last year.

Thank you, luvsmuzik. Exactly. I need to draw almost 100 nebulae for the game. I'll go crazy if I do not get rid of the routine. The only thing that I will continue to do in Photoshop: the composition, the addition of stars and distant galaxies. There is another question with how I will paint nebulae. I have not decided yet. Initially, I wanted to create renderers with channels for painting, that is, the nebula is colored in conditional red, green and blue colors, so that later in photoshop on these channels I can start any others that I want. Now I see that even the conditional colors look interesting, and the nebula with algae (the last one published), which I painted completely in TG, demonstrated that the TG can handle it on its own.

Photoshop I now use only to change the total exposure and there for a slight correction of the exposure near the stars, but for a specific seed, we can simply make the star darker or brighter.

That's really surprising! I might actually try this approach and just work around the light! I never thought about that. I was too busy seeing dense spots, or bare spots in my clouds and wanting to move my lights around them to see the lighting effects. Thanks for that.

As for the variations in total cloud forms in repetition similar to the Crab Nebula, I would imagine your original shared idea of using a base density fractal, and than separate warping passes and fractalization would create the variation needed. Especially a final large warp for those "lag" features if the the fractal warp shader with roughness turned down a bit doesn't create it. I'm actually working on a project with similar uses in order to create variance, but be on "track" with the whole form, while using the original form for each new element. It also also adjustments to all passes (cloud nodes) a bit easier without having to look into multiple density shaders.

It's cool that it's procedural. Perhaps this can be useful for animation. In the case of a static illustration with a nebula, I still prefer those stars that we already have for the game backgrounds. There are some special requirements for the game, which we took into account. Unfortunately, this is just the kind of thing that does not fit into my formulation of the "fully procedural nebula".

Yes, I've seen these nebulae. Here is the site of this man: http://www.salmonick-atelier.com/. These are the best nebulae in motion that I have seen. He created them in Houdini. As he himself writes, it took about 5 years. I suspect that 1 year left to create the basic scene, and 4 more to render)) These are very beautiful, artistic nebulae. But, nevertheless, he, and even more so to me, still has much to grow.

Hannes, this is an interesting moment for me. Could you tell me more precisely what exactly makes the last nebulae less natural than before? And the word "before" - with which old nebula, for example, do you compare? This is an important point, because over time, the vision is lost and criticism is needed.

Regarding the file, in fact I can not show too much, but I can now share the clip-file of the main form.

yes! Thank you for this share! I think what most of us were doing was using the Density Fractal preceding our warps for our cloud layer. I had tried some warps but could not get the opacity you achieved with your large fractal warps. Terrific stuff!

I will continue to experiment adding the Density Fractal back in, masking the warps, anything else I can fiddle with, but thanks again!  :)

I was stuck using much smaller scales (especially smallest scale), and single PF warpers, which only push vertically, creating noise. Honestly surprised I never thought of the redirect shader after the vertical warp discussion. The 3 axis redirection is what is specifically creating the small scale detail as it basically simulates small scale cloud build up by being warped.

As for the problem with vertical stretching of clouds - both ways that I offered in this topic work:

Quote from: Matt on March 14, 2018, 05:35:45 PM
You should either use the Redirect Shader method or the Vector Displacement Shader method, but not both.

I forgot to mention that you need a Build Vector node if you use the Vector Displacement method.

Use one of the following methods, but not both.


Method 1 - Redirect Shader:

Use 3 fractals that generate displacements. Connect fractal 1 to the 'X' input of the Redirect Shader, connect fractal 2 to the Y input, and connect fractal 3 to the Z input. The Redirect Shader is now producing 3D displacement (vector displacement). You can then use this as a warper for the Warp Shader.

Fractal 1 (disp) --\
Fractal 2 (disp) --> Redirect Shader --> Warp Shader
Fractal 3 (disp) --/


Method 2 - Build Vector and Vector Displacement Shader:

Use 3 fractals that generate colour or greyscale. Connect fractal 1 to the 'X' input of the Build Vector, connect fractal 2 to the 'Y' input, and connect fractal 3 to the Z input. Connect the Build Vector to the 'Vector function' input of a Vector Displacement Shader. The Vector Displacement Shader is now producing 3D displacement (vector displacement). You can then use this as a warper for the Warp Shader.

Fractal 1 (colour) --\
Fractal 2 (colour) --> Build Vector --> Vector Displacement Shader --> Warp Shader
Fractal 3 (colour) --/


Method 1 is simpler for your needs because there are fewer nodes and conversions. But Method 2 is simpler if you already have a vector to use as displacement, e.g. if you have a vector displacement map, where you don't need to use a Build Vector.

I do not think that this is due to small details. The main factor that allows to obtain small details is a combination of factors such as the size of the cloud and its density (as far as I could understand it). And, of course, the presence of small-scale details in the fractal sent to the warper.
Title: Re: Nebulae
Post by: luvsmuzik on April 12, 2018, 10:13:11 AM
So now I am wondering if method 1 and method 2 suggested by Matt can be merged if you do not apply displacement with the build color method. I shall soon see.

Don't get me wrong, they look absolutely stunning! But they are so extremely crisp, that they might look like something else (no idea what, but I like it!). Even more like particle simulations.

As for the variations in total cloud forms in repetition similar to the Crab Nebula, I would imagine your original shared idea of using a base density fractal, and than separate warping passes and fractalization would create the variation needed. Especially a final large warp for those "lag" features if the the fractal warp shader with roughness turned down a bit doesn't create it. I'm actually working on a project with similar uses in order to create variance, but be on "track" with the whole form, while using the original form for each new element. It also also adjustments to all passes (cloud nodes) a bit easier without having to look into multiple density shaders.

WASasquatch, I did not quite understand what you are offering. Could you elaborate, or in other words describe what you are proposing?

I tried today to achieve the effect of "blowing light clouds off the surface of heavy ones" with the help of a fractal warp shader and came to the conclusion that it does not provide any additional capabilities, compared to using an input or merge warp shader in combination with a power fractal shader. He is even capable of a little less. But, it seems, it is more productive.

On the contrary, your initial example clip setup has a smallest scale almost 5x the base scale. The warping creates "holes" (in a terrain this would look bad) in this base form, while pushing them, creating build up along the edges of the wholes, creating that small scale debris details. I attached a image that shows these low level plumes that build up and capture light

Here is a very simple example of varying repetition. You won't really see in it the render as the area we're looking at really has no really definition but what the cloud layer is forcing in due to extreme contrasts, but take a look at the last merge shaders preview.

There is clear repetition, but no shape is the same. Adding further warping, translation distances, can improve this method.

Edit: added some test renders with different seeds, and doing another at smaller scale, but will take longer.

Smallest scale - 76 meters, not 6000. Lead-in scale 26000. This means that the smallest scale is not 5x, but 340x smaller than the largest. But, as I said, it does not matter. You can get a small detail (for example, to turn a cloud into one point) if you get the desired fractal for a warper even having a minimum scale 5000.

The reason for the appearance of such holes is not that we have too much difference in the scale of small and large parts. The fact is that you have too high and sharp peaks. This can happen on any scale. Try to adjust the fractal for the warper so that there are not too steep slopes for all octaves.

I understand, thanks for *.tgd and examples. Honestly, I do not think I can use this method. I have a suspicion that in order to sufficiently pull the part, you need to add a large number of such transformations. Their number should exceed 10-15, and still, if there are enough small details of their duplication will be visible (although, perhaps, changing the shape of a new layer can fix this). All this, my computer just will not survive. While there are doubts in this method.

While I did this:

[attachimg=1]

[attachimg=2]

It's: (Сloud layer "A" + warping) - (Сloud layer "A")
It works fast enough. But this method is also not good in everything and it can be used only as an additional one.

Big thanks, Stormlord! This is a newer version of the file, it's better than the one you asked for because it has fewer vertical or horizontal structures. As I wrote to you in PM, I can not immediately know what I can sharing, and what not. There is a possibility that these nebulae will become an independent product that will cost some money. I posted this file, because I thought it was something I could share for free with everyone.

This can happen on any scale. Try to adjust the fractal for the warper so that there are not too steep slopes for all octaves.

As far as I can tell, octaves are directly related to your scales, predominately, you smallest scale. These peaks are not part of large scale PFs, the smallest scale directly relates to peaking.  For example if you check continue peaks, and amp up the maximum peak scale and displacement with a smallest scale of 0.025 and a maximum of 1 with a lead in of 1, you'll notice it will be full of ~+/-0.025 meter peaks.

As for repetition, I'm not sure what you hope to achieve? With expansion you have plainly visible repetition created by the source explosion, and the source explosion is never continual and only creates so much variance. The rest is independent formation of time through much slower forces, some even in different directions from cosmic sources rather than the radial source. And, again, with large scale fractalization, with low roughness, I'm not sure how the shapes could appear very similar after added warping.

I did not play with it in TG, I do it in Photoshop. Honestly, I did not even attach importance to the presence of this setting in TG. Although it would be possible to try to do this, since I want to make a fully procedural generation of the finished result. I think I'll play with this in TG. In general, it is rather strange to see such a setting in TG. I adhere to the idea that if there is not enough contrast (or something else), then you need to achieve the desired effect by adjusting the scene, and not using post-processing (if I correctly understood, this in TG works just like postprocessing and does not participate in the mathematical calculation directly during the rendering). But the cases are different, I agree with this, and it's convenient to have it on hand if the scene settings do not help or are too complicated.

Many people like to do this, but consider the fact that many photographs look the way they do because of the way the film/process/sensor reacts to different levels of incoming light after the universe has summed all the light together. If you're making a texture for a game where the engine has its own post processing then you should output linear EXR and then evaluate how your texture as it appears in game. But if you're making standalone finished pieces then post processing is an important dimension to consider when making your digital art look different from someone else's. If you ignore the importance of post processing you are limiting yourself to just one point along this dimension. Light works in a particular way in the renderer to simulate what the universe does (adds light purely on a linear scale), so some things are only possible with post processing.

Matt, thanks for the comment! Perhaps in my report, I did not place enough emphasis on the fact that I do not attach much importance to post-processing inside the Terragen, and not post-processing at all. In Photoshop, I then perform the exposure up and down, increasing or decreasing the contrast and saturation. And the text you quoted may not fully express what I wanted to say. It was supposed to end with something like this ".. before you were convinced of the physical reliability of the scene.". In other words, I prefer to process that photo that was obtained with a working camera, rather than the one that was obtained with a camera having a sensitivity dip somewhere in the middle of the brightness range.

Regardless of what approach is better, the results can't be argued with, what you are doing is working rather well, though like Matt said, if this is going to be used in a engine, linear EXR is definitely the way to (at least with modern games). I know older engines would use textures/backdrops but this is becoming more dynamic with the use of high range shaders.

The chromatic aberration effect really adds to it imo. I've always like it.

What two approaches are you talking about? I also like Matt do not deny the importance of post-processing. Simply, I say that post-processing should be POST, that is, when we have already received a realistic model and now we want to achieve artistic expressiveness. But I, as usual, could misunderstand some things, because my English is not perfect. In addition, my position is my general approach, which may have exceptions or even be the basis for a different approach. For example, you can wipe the lens of the camera with sandpaper and take pictures, with a grunge claim - in this case, post processing is included in the main process of creating the image. Although by definition can not be called "post-processing", however, in essence it is it.

Our game engine has some post-processing, but it will not affect the contrast or brightness of the picture. In addition, those images (that I'm sharing here) are not the ones that will go for our background, for example I can not do aberrations or make nebulae so bright.

Yes thank you! I love aberrations. It's great that someone noticed this ) And here I have a legitimate reason to use them - on all real space images and can be seen quite well.

Oh I just mean the different approaches to post processing, whether just in TG or post-processing in another program. There is a lot of power in post processing that TG can't offer.

Yeah I figured the images you were sharing were just personal "polished" iterations. I imagine for the game it'd be much bigger, and a little more flat for the post processing in the engine.

I've always done similar in a lot of my work, I actually didn't know the name of it for a long time (and forgotten when I did figure it out) and had to reproduce it based on memory in PS which didn't yield the best results. I'm still trying to a effect I like the best to make a photoshop action out of.

Though even that's changing, now we see professional photographers, designers, and promotional artists incorporating it in ads, commercials, movies, etc. At first it was a artifact of lenses, but now is seen as "hyper realism" as ALL lenses produce chromatic aberration

Our eyes does have chromatic aberration too.
But we have DOF, myopy, presbiyopi and what not too.
Some of those we are aware, some not so much.
Should every image contain those things? You can of course use them as an artistic choice whenever you want.
But like the shaky cams in movies it feels cheesy, bad and the easy way to do something after a while.
So when someone says, he likes chromatic aberration, i get that feeling that he tries to put it in anything he does.
Basically what i don't like is the overuse mostly.
I like clear images because i hate blurry images (i have goggles). But i like of course when those "imperfections" are used in good places.

I don't care if this or that is used now much. It won't be 5-10 yeas later. Probably something"new (!)" will come.
From the hype of HDR TV's (for itself it is a good thing actually) it looks like something on that line will be overused for a time.


Edit: Screw that. When i read what i wrote it felt more like i have an obsession. Should take a break probably.

Than again, if someone incorporates something like this, it would be considered part of their style. I'm not sure that's something to argue against.

For example I feel with Denise's work it's as if we're viewing a raw image of a nebula via some sort of probes high definition digital camera. Without post-processing the raw image would have peripheral lens aberrations due to light exposure, and also chromatic aberrations from the overall lens curvature.

Motion blur, lens artifacting effects, lighting effects, all "imperfections" of lenses, whether your eye or camera. When you work with things yourself you can be bias to this because your tastes are vastly different as an artist yourself. However, you can't argue with real world applications where everything is littered with effects for hyper realism because the average person likes these effects (moth to light effect). Chromatic Aberration is used in movies like LOTR and The Hobbit and looks wonderful all throughout. There weren't clearly "cameras" in this world, but that's what they did. It's used really in a lot of situations where it's not even noticed because it's methodology is used for a new effect altogether like HBO (I don't know what this stands for and have only seen it in HLSL form) where you take a Chromatic Aberration and than blur it, and sharpen it, and overlay it, creating a appearance of more detail, especially on already detailed areas. The shift of the aberration is only one pixel in opposite directions.

It's also really popular in science fiction and space stuff in general, like everything modern uses it pretty much as far back as Battlestar Galactica on Scifi.
Title: Re: Nebulae

"hyper realism" of what? Cameras,photos or how we see the world?
Even if you use googles that have cracked glasses you won't see the cracks after a while.
The world will look perfect despite what you have in front of your eyes.
Popularity doesn't mean "good".
Having to adjust the effect shots to the real shots is one of the things i can understand and have no problem.
But putting the same things "always"to shoots that doesn't have those kind of problems is laziness and just because of"they like these" attitude and has nothing to do with art in general. For me at least. But as i said they have their places of course.

Technical limitations of the past (and now) are one of the problem that some things are still considered for some ok.
With 4K and maybe latter 8K you will look at movies done today and say 40 years later"Wow what shit have they done to that movies?".
You can't use the same techniques (at least at the same pixels levels) on 4K movies. It wouldn't look "hyperrealist" it would look bad.

My eyes have those kind of imperfections. When you add those imperfections to what i see those imperfections get doubled.
Show me how it should be as clear as it can be. Then my own imperfections will do the rest already.

There are more nuances of course.

Can you go more realistic then a documentary? When i look at the word documentary something like these come up:

*- Which serves to document (record and: or illustrate) a subject of, related to, or based on documents
*- A film, TV program, publication etc. which presents a social, political, scientific or historical subject in a factual or informative manner
presented objectively without the insertion of fictional matter
*- A factual and objective presentation

Would you add those imperfections (or use even black and white today) to a documentary to get "hyperrealism" (I hate that word too by the way :) ) ?
Title: Re: Nebulae
Post by: Hannes on April 30, 2018, 12:45:19 PM
Well, here are my two cents. It all depends on what you want to achieve.
If you want a perfect digital image, then don't use it. If you want to make your image look like a photograph, then it's OK to use chromatic aberration and all the other stuff that imitates lens imperfections. Lens flares as well. Also something that photographers usually try to avoid. But an image with the sun right in front of the camera without any flare might look unnatural. Somehow dead. Or just digital.
Of course all this should be used correctly, when you want that photoreal look. Some people use DOF or lens flares just because they they can, even if the whole image looks cheesy in the end, because it's not used correctly. OK, incorrect DOF can be used as an effect as well, if you want to make your image look like a miniature.

Imperfections are quite interesting and inspiring. Imagine overdriven electric guitars. The sound is created originally by using a tube amplifier that is strictly speaking a bit too weak, so the sound is overdriven, but it sounds good, since it's a harmonic distortion. This is an imperfection. There are effects devices that simulate exactly that. Should we now say, that we shouldn't use those, because a guitar has to sound like a guitar? Imagine the sound of a Hammond B3 without the imperfections of the amp and the Leslie speaker. Boring!!
Once again it depends on what you're after. When used moderately dosed it's great, otherwise it sounds or looks awful.

I know, that I am one of those who relentlessly use chromatic aberration, because I want to make my images look photoreal (as far as I am able to). I might tend to overuse it, I know, but if I put the original image and the one with CA side by side the difference is very subtle to my taste, and it adds some unexplainable organic feeling I think. Hard to explain...

Would you add those imperfections (or use even black and white today) to a documentary to get "hyperrealism" (I hate that word too by the way :) ) ?

Depends on the documentary... Even dinosaur CGI uses Chromatic Aberrations. Also a lot of science documentaries these days, even some older stuff like the Chasing UFOs series. You keep giving examples where it's actually used on a regular in modern applications. Even used in JW and just about every modern movie. Even older stuff like Tron Matt worked on.


Again you are arguing personal tastes with art which is about the biggest no-no there is. It's like art class. Any style someone adds is not against the curriculum. It's their style. As long as the base work is completed.

I also think when you think of CA you're thinking of high range shifts and not subtle 1px shifts you probably aren't noticing in most it's used (especially after dynamic scaling). It actually fools the eye into more depth and detail. And yes, again it's popular in hyperrealism is sketches, final photographs  of sculptures, etc. Again, because of it's ties with realism, despite debate.

Also when it comes to making money in media, what's popular is what goes... That's plainly evident in just about everything. The moth effect is the biggest trend in cinema. Over using lighting effects and CGI relentlessly to attract audiences even if the movie is absolute crap. 

I feel like if you aren't teaching a class where some is willingly coming to learn from your style, it is fairly rude to tell someone what to use or where to use use it in art. It purely goes against the principles therein and why just about every major artist never took a class, and that's what personifies them. Following in line with set rules isn't really art. It's fabrication. Like the Asteroid I did. I was trying to make an Asteroid. Not art. It follows real world settings as best I can. I fabricated an asteroid. It isn't suppose to represent anything meaningful or from some deep part of me. Though I do intend to add it to a art piece at some time if I can ever get a nebula scene looking nice.

I wrote too much and still looks like i could not write clearly what i actually mean.

Using those imperfection in renders is not realism (like showing how the real world looks).
It is only mimicking the look of cameras, photos.

Labeling the later as "realism" is what i don't like.
Otherwise nor chromatic aberration nor DOF etc. or whatever in itself  is what defines art.
What art is is quite another very subjective topic.

I know for example that Hannes uses it mostly and i like to tease him about that mostly :)
That doesn't mean that i don't like his pictures. Quite the opposite. 

Anyway. Sorry Denis.

I guess what I mean isn't easily translated either. You know what you are talking about, which makes you inherently biased to it's use, as you know what it's from, what creates it, etc. This however is not the case with the general populous. In fact it's the opposite, they're ignorant to most every subtle effect, but overall add to them the perception of detail, appeal, etc.

For example, no one is generally using it to recreate a camera effect, they're using it as an effect in general, void of specific camera/era. For example, it's use in science fiction. For some reason it's just been related to space and such. Games use it on the regular, as well as movies and tv shows in this field. Regardless of your tastes, if is generally well perceived, and again is part of a personal style, is the effect itself art, no, but it is only a small variable of the larger picture.

Art is not subjective, it's relative. You can judge other peoples art, but generally, it means nothing. It's relative to what they like, you know? Eye of the Beholder, and all.

Hey guys!

So, I can take a little breath and gradually share what has accumulated over the past few weeks. This is one of several dozen processed images that Terragen gave me.

This is not the final result to which I aspire. As a final result, we need backgrounds for the game, where the nebulae will be much simpler in form (this nebula will be cut into several simpler parts), darker and they will be on the third plane after space ships and planets.

However, I just can not reconcile with this and wanted to see and share with all my nebulae in a way that they are the main goal of my work.) And this stage, I think, will be more interesting if we are talking about working with nebulae.

WAS, yes, there is some unrealisticness, I admit it. In fact, after my last publication, the network of nodes has not changed much, and even simplified. This is because I 2 months was not engaged in its improvement, but in rendering a large number of nebulae and preparing them for embedding in game backgrounds. The network of nodes was even slightly simplified.

This unrealistic can occur in all components of the image. Some of them could show up due to limitations in the performance of our computers, the other part because of the incompleteness of the mathematical model. Also, some things may not look realistic, but it's more interesting, and here we deliberately moved away from the original concept of "repeating nature." There can be many reasons. But it would be more interesting and useful for me to find out exactly what things made you think so?

I think someone else had mentioned it before (Hannes?) I haven't gone back through the topic. But your earlier iterations seem more natural, and like Nebulae you can find from Hubble and such. Not talking about repeating nature or anything, but the overall look. They now seem a little unlike nebulae, surreal, exaggerated, dreamy. The latest image reminds me dynamic fluid particle simulations for stress tests. They create a lot of shapes like this. Like this exaggerated one for a car doing a donut:

(https://i.ytimg.com/vi/RuZQpWo9Qhs/maxresdefault.jpg)

One thing that may help is not so many small forms going all different directions. There should be some sort of directional flow, even if on a few axis's. Currently it just seems formless and chaotic, like a test. I don't know. I'm not trying to be rude, only trying to help you remember comments you had made earlier about needing input if the idea was lost and didn't look real.

Thank you for the remark about the multidirectional small forms, I will draw my attention to this. As for my initial desire to get the most realistic nebula - well, you see the result of this desire, available to me now. Perhaps if I spend a few more months or years, I will get even better :)

By the way, the dreamy sensation is probably because I began to add glare (for bright light sources) in the post-processing. In addition, I publish these nebulae without additional stars — here only stars actually illuminated the nebula in the TG.

And now I'm just laying out another render.

From page 15 on, the Nebulae take on a surreal, unrealistic form. More like 3D tests, than accurate nebulae.

All these look like nebulae you can find. The latest, I can't find any references IRL that look like these. Star or not. I can in visually exaggerated films probably.

WAS, it's simple. Old nebulae are the result of painstaking design in Photoshop of one or two basic TG renders, and a large number of small parts other renders. But the last nebulae are almost raw renderings. And in fact I'm flattered that you compare them, because I spent about 1-2 days to collect the old nebulae in Photoshop, and now for new nebulae it takes about 2-3 hours for post-processing (original images size 2048x2048 px).

I will remind you that for the game these new renders I will also cut into pieces and delete unsuccessful places, add stars, add beautiful gas streams and other things. However, this nebulae will be darker, as they will go to the background in the game scene. Therefore, while they are still bright and contrasting, I decided to show them to you.

Sjefen, I had a conversation today with my director about the sharing or sale of the scene file, so that you could independently render the nebula in the appropriate size. As you understand, the work was done on studio money and therefore I can not be the sole administrator in these things. The result of the conversation: unfortunately, we can't distribute the files of the final scenes and images in high resolution until the moment the game is released. And the release date of the game has not yet been determined, I think it will not be very soon. But thanks for the interest shown and sorry that I can not now help anything, except for the preparation of wallpaper without watermarks. Your interest increases the likelihood that in the future it will grow into a complete product for sale.

Maybe pitch the idea for promotional posters? I see the game is working partly of community action, perhaps that could play to your advantage. I know I'm already interested in the game myself, and would love to support it if I could. A poster campaign may help with sales as well as interest just cause of the nature of the mesmerizing high quality posters reaching out further than the initial game audience, and subsequently who they share their new poster with.

The relatively low cost of 3rd party poster producers these days probably wouldn't require much effort. There are even some on-demand retailers still out there that work based on individual sales of a poster.

I had one of my first "good" renders in TG printed when I was younger. Due to resolution limitations it's more a post card but I was super proud to see it physical.

Technically you can upscale the image in PS without destroying the details. I have a method that works for me. Drop the image into PS and change the document size from 100 percent to 110 percent. Make sure you upscale only by 10 percent. Then repeat the same with 10 percent again and again. For some reason if you try to use bigger percentages the PS will destroy the details. Not sure why but this 10 percent steps worked for me several times. You might need to pump up the dpi settings also if it low.

I tried on this document, and recorded the method I used. The document DPI was set to 300 like a lot of print. The result seemed blurrier than using a regular resize with settings set for "Bicubic Smoother (Best for enlargement)".

Here is the action of what I did. Upscsale is 200% from original resolution.

I try not to interfere with the strategy of promoting our game. Yes, I understand that there are people who are ready to support the project now. Thanks for the willingness, WAS. I can only say that my management adheres to the strategy of unexpected appearance, and the development is quiet and as long as we need it.

Yes! I tried it yesterday, and it really works. Thank you for the tip! On the GIF, the comparison of a x3 increase by 110% and a single increase by 133%. (Sorry Was, but I made this test before I saw your experiment, so I publish it.)

However, I think Sjefen will not be enough. He does not need to save small details when upscaling, but to get new small details with rendering a much larger size.

Wonder why it's blurrier on my PS. Using PS filter for enlargement bicubic smooth works better than that method. I didn't do just 133% though, did double size at 200%.

Can someone run that recording I made in their PS and post results??

Perhaps this is because an increase of 110% you also did using resampling "bicubic smoother". The mode "automatic" with a step-by-step increase of 110% better preserves the details.

In any case, there is a way even better, and it can even help Sjefen. This is the resample mode "preserve details 2.0". Tthere is in my version of Photoshop CC 2018, in which this feature first appeared. It allows you to perform a significant increasing image size without losing small details.

I have not, unfortunately. It and literally hundreds of projects sit awaiting a decent computer. I've tried ton come back to it but always end up canceling the renders. Being in a RV in the middle of no where with just my son for entertainment, I end up using my PC a lot. Lol I wish I had another one going. I dare not abuse my fiancee's little Asus touch netbook. :P

I could do lower quality renders like I do with other stuff, but with nebula's it just doesn't feel worth it to me. The quality loss is just too much for me to get over.

BG 035 is really nice, it reminds me of remnant supernova. I am curious, would it be too much to ask for you to paste your Render node here? I'm curious what settings exactly you're using, I know I can't do higher than MPD 0.6 and AA6 but still struggling with some smaller details and at this point I don't think it's my fractals/warpers.

Great shots again! :)

May I ask about a concrete render time?
For my animations I always have the aim to reduce the render time as much as possible. My personal limit is about 2-2.5 h per frame. above it doesn't make sense for me. I guess for usage in a game you follow completely different criteria?
Title: Re: Nebulae
Post by: Denis Sirenko on October 22, 2018, 10:06:46 AM
DocCharly65, thanks!
Yes, of course, I need fewer frames than necessary for animation. I could afford about 100 hours for one such render with the size of 2048x2048 px: https://planetside.co.uk/forums/index.php?action=dlattach;topic=23403.0;attach=83510;image

Fortunately I have 5 PCs for rendering too, but for other reasons. When I started my film it should have been just a 5-10 min Music video for fun and I was happy to have my new "gaming PC" for rendering in 2014. Then I kept it as rendering station and got a new PC for gaming... then this one had to render too... same happened again and again... now I won't buy another gaming PC because I anyway know what will happen to it... I keep being the bad player I am on the PS4 :)

I think the improved adaptive sampling that Matt is working on for the path tracer should be helpful for these nebula renders (lower noise for same time/faster renders)...

Title: Re: Nebulae
Post by: Denis Sirenko on October 23, 2018, 06:24:11 AM
DocCharly65, by the way, yes, with Oshyan for an animated movie, we have jointly reduced the rendering time of one frame to 1-2 hours. So here such optimization is possible, if you make a smaller frame, and the quality is a bit lower. But we still have a problem with the twinkling of stars, which still does not allow rendering so quickly.

The improved adaptive sampling is available already in Frontier builds. If you have current maintenance you have access to them (4.3.09.frontier at the moment). The options are in the Edit Sampling dialog, "New adaptation curve" and "Robust adaptive sampler". They are still being worked on though, and should get better still. I do think it may help with the twinkling stars...

Oshyan, our maintenance has expired. Current TG version is 4.1.25 and I haven't this functional and I think that in the near future I will not be able to upgrade to the latest version.

Ah well, it will be waiting for you (and further improved) whenever you can justify renewing Maintenance. In the meantime I haven't forgotten about the nebula animation and the new adaptive sampling will be a good test for it. Just need to wait a few more weeks until it's more finalized.

No, these are not only renderers in Terraggen, but also work with them using Photoshop. In Terragegen the form, lighting from several bright light sources (about 10), aerial perspective (gas) and colors were obtained.

Almost raw render can be seen here:
https://planetside.co.uk/forums/index.php?action=dlattach;topic=23403.0;attach=83510;image (in Photoshop added stars and exposition in some places)

or here:

or here:
https://planetside.co.uk/forums/index.php?action=dlattach;topic=23403.0;attach=83302;image (add exposition)

The using Photoshop is mainly due to the fact that we need a variety of forms for game backgrounds in which the art-director constantly makes edits.

Yes, it also seems to me that this is not a matter of path tracing. There is just a lot of clouds of a rather complex shape. You can try to just reduce their content. Before the render was much faster, because I rendered a flat cylindrical layer of clouds, looking up at them. And now the nebula is a big sphere that we look at from the side. This is better of course, but longer.

Perhaps some day the warp shader/redirect shader won't be as heavy as it is and it would really speed up rendering. They both super slow down displacement and clouds. A V3 with a nice setup will render decently but as soon as you warp for shapes you're looking at double the render time +. It's a little unfortunate.

A V3 with a nice setup will render decently but as soon as you warp for shapes you're looking at double the render time +. It's a little unfortunate.

I agree that the warper slows down greatly. However, I am sure that the use of two fractals through a warper is a more complicated operation than the addition of two series-connected fractals. Because in case of a serial connection, you use the sum operation, and when using a warper, before reading the value of the new color value, you must first find its location relative to the current point of space (construct a vector from the target point). As a result, you get a very valuable effect - the preservation of the total amount of white color, i.e. compliance with the law of conservation of energy (in the form of matter).

On the other hand, it did not seem to me that the redirect shader works so badly. I think so because if you leave one fractal connected directly to the warper (I'm talking about the *tgc, which I shared before), the rendering speed becomes about 2.5-3 times lower, as it should have been if I could connect three fractals to the warper WITHOUT a redirect shader at all. At least in my case, I did not see a large tax on the use of the redirect shader.

I would also like to say a few words about optimizing the rendering of my *.tgс using a non-critical form simplification.

You can make a small optimization not due to the rendering settings, but at the expense of the nebula geometric form. Several elements of the node network contains opportunities for optimization.

One possibility is to use a warping fractals. You can use not three fractals on the warper through the redirect shader, but one, right on the warp shader. Three I used to avoid the appearance of explicit directional forms, which were sometimes deliberate. But sometimes they did not appear at all. This way you can get additional rendering speed by limiting the selection of good seeds. I could not go on this because I needed a lot of good seeds, a lot of differen good forms. Using only one fractal gives x2.5-3 rendering speed increase, as I already said.

However, reducing the number of fractals on the warper will require additional adjustment of these fractal. This is due to the fact that the form will also contain three times less distorted elements. This means that it will be necessary to complicate the shape of a single fractal by increasing its displacement, roughness, clumping of variations and other. This is to your taste.

The rendering speed can also decrease significantly if you use less gas (evenly distributed fog) in the spaces between the nebula dense structures. This can be done by increasing the contrast of the fractal so that pure black areas appear between the dense structures. Or using color offset. At the same time, it is necessary to ensure that the transition from black to white through gray is smooth, without any obvious lines (although in some cases they can imitate fine thin structures of gas or dust).

You can also reduce the smallest scale for a fractal. I set it up for images of 2048x2048 pixels. For smaller sizes it can be reduced.

Hey guys!

I have a question. Since I am Russian, I have a question for those for whom English is their native language. On the gif here attached, you see a piece of video that I will soon publish.

[attachimg=1]

This is one of the 12 nebulae that will be there. The total duration of the video is 5,5-6 minutes, in 4K, approximately 25-30 seconds for one smooth slow flight around the nebulae of different shapes, colors and complexities.

I want to call it "The birth of not our Suns" and from this title the video will start. I want to say that nebulae are the cradle for stars; in the nebula, stars form in the future, each of them could potentially become for new civilizations what our Sun is for us. But this is not our Sun.

Tell me please, do the English say that? Are there any mistakes? Or maybe it sounds weird, but not a grammatical or some other mistake?

"The birth of not our Suns" — it "reads a bit oddly" or is it just a mistake and it will be wrong to say so? In other words, can such a name be attributed to "a bit unusual, but in general there is no rule that prohibits saying so." The fact is that I strive for a slightly unusual form, but at the same time I don't want to make a mistake. In any case, thanks for the alternatives, the second option seems most interesting.

Oh, Oshyan... :) I really do not want to disappoint you, but I did not use TG for honest rendering of animation in 4K. I have a complete lie here) In fact, these are flat nebulae that were generated in TG and which I arranged in 3D space in layers at some distance from each other in After Effects. But even in the After Effects, rendering a 30-second movie with a 4K nebula takes from a few hours to a 2-3 dozen hours depending on the complexity of the scene! Note, this is generally without calculation of lighting in 3D space! Just flat layers in space to which we look at the changing angle. Nevertheless, I can say that TG is an essential part of the entire project. Thank God I did not call my topic "Fully procedural nebula", although I mentioned that I strive for this)

Hi all!

Finally, I can publish the result of a long work in free time. But I immediately want to say that this is not exactly the video for which I published a teaser a few days ago (it will also be, but later). It is neither worse nor better, they are both about the same, and in both videos the great music of a great musician sounds.

I got a short meditative-informative video. Adjust your seatback, make the sound louder, and enjoy! And do not forget to choose 4K, the compression algorithms do not spare the dark space.

Astonishingly beautiful. I really got carried away. Music is superbly fitting too. It makes you feel very small if you realize what's out there....

Gorgeous and impressive work! And you really can't tell it is layer or slice-based in most cases. Like the music too. Well done!

Fantastic! Love the Nebula at around  3:10.

Great to see this unusual use of Terragen. reminds me a little of what Richard "Doc" Bailey was doing with Spore - nice to see very organic looking animations.

Thanks for the tip, I found it. Yes, there is something similar. And "Spore" reminded me of another program - Apophysis, in which I even did something.

Thank! That is why this nebula shown on the preview of video, despite the fact that it was made a long time ago and was generated with old version of the algorithm. It's called Gelfon Esto :) It's needed quite a lot handwork after generating in TG. So it is unlikely with this algorithm would complete the work on nebulae to the present day - we needed almost a hundred of backgrounds with nebulae.

Using the technique of Master Sirenko I made this. This is 2 nebulae render comped together with additional stars in Photoshop. Not even close to Denis insanely cool renders but kind of okay.

Thank you. My render need lots of improvements for sure. Like even though it is a 3d render, it looks very flat. I feel no sense of space at all. Guessing it is a problem of light. Like the position of it.

Perhaps the nebula is not enough density and needs to be made denser. Sparse nebula shows its shape badly. Or maybe the geometric shape was lost at the moment of the combining of the two renders due to inconsistencies in lighting.

Interesting. More dense? But that will block more light in general and the scattering will be also less... No?
Title: Re: Nebulae
Post by: Denis Sirenko on July 31, 2019, 06:58:29 AM
Yes, of course, here you need to look for a balance. And I could be wrong about the density, maybe the matter is different. What is the name of the *.tgd file you use?

It was the first shared file. "2017_06_01 Nebula (by Denis Sirenko)"
Title: Re: Nebulae
Post by: Denis Sirenko on July 31, 2019, 10:51:45 AM
Understood. There are three cloud layers, for each of which you can independently adjust both the density and the coverage. Need to experiment. Or/and try to move the sources of light - maybe they just do not in the best way reveal the shape for your seed.

I think this is where I end my experiments with nebulae. All the tasks that needed to be implemented for our game were successfully completed. I have gained invaluable experience working with procedural graphics, which I have never encountered before. I am sure that the choice of TG was correct. It is unlikely that I would have survived by painting 97 backgrounds with nebulae measuring 2048x2048 px manually or somehow.

It really was one of the most interesting adventures in recent years. Every victory that I gained in understanding the work of individual mechanisms (specific for TG in particular, and for procedural graphics in general), as well as every victory in coming up with my own solutions based on these mechanisms, is what really fascinated me. This is the tool that I am now armed with, along with 3D and 2D graphics. I know that the next iteration of refinement of the generating scene with nebulae would make nebulae better (I see many ways), but I am limited in time, the next studio projects do not wait, and personal projects are not directly related to nebulae, so I will have to leave everything in the form in which it is now.

And thanks again guys! You have always supported me both technically and spiritually, despite the fact that I was only in my own topic. You are true purebred enthusiasts and I wish you creative success! Perhaps I will come here again, but this is unlikely to concern work on nebulae.
