Hey guys
I have made a picture (WIP) - and I would like to have more realistic lightning, grass, atmosphere and so on.. I have tried alot of things to make it more realistic looking with this beautiful blurish effect that many of you experienced users make use of..
So far, I have found no sucess in my research.. Therefor I will now ask you guys if you may have some experience/suggestions you might wan't to share with with a gold fish like me..
I have uploaded my picture as it looks right now, I still need to change a few things on it but as you can see, it's very basic I guess.. There's no "WOAW!" About it..
I only know about the basic settings like position the sunlight etc. but it doesn't look any realistic to me..
I hope for the best:)
Cheers,
Mike
PS. the picture is too large to upload so you can look at it here: www.sp34k.com/ps
If you want a real wow factor, personally I'd move the sun so it lights up that mountain to the right, and use some localised light sources around the cottage. A creamy yellow sun with a lighter blue (as opposed to the grey-blue default) atmosphere may give you the lighting you're looking for, it's really about experimentation though, trying different colours and strengths for light and the atmosphere. If you want it to look cold and wintery then I did a render ages ago that looked quite good, I used 2 suns. One was yellowish with the strength increased a bit and glow in atmosphere off, the other was blueish, can't remember if I decreased the strength or left it alone.
Hey PG
Fast reply! I wonder if you were waiting while thinking "I guess Sp34k will make a topic soon!" hehe.. Anyways...............
I'm actually look for the wintery atmosphere as you spoke of, I just haven't succed yet.. But thank you for explaining this to me, I will try and use 2 suns which I have never thought of using before.. I thought using 2 suns would be wrong? But I guess I was wrong again :)
I have tried to work with the Light Source but I can't seem to find any effect on it.. I'm not sure if I use it the right way but isn't it just about placing it where you wan't it and increase the diameter and strenght?
I sure have something to work on here while it's raining outside :) Wonderful!
Cheers buddy,
Mike
I have just looked at this and here are the good news: this render has everything you need already in there. Your one and only problem is the lighting. It's the main issue for most users that struggle with perfecting their scenes. It's always the lighting (well almost always).
Yes, you could for example give the stones on the path a more reasonable size, and yes you may tweak this or that, but the overall impresson comes from the composition and the lighting. You image is too uniformly lit and, like you were trying to bring out detail in the sky and in the shadows on the ground at the same time.
Your "brain" will compare this with a photograph, and tell you that it looks wrong, because the dynamic is missing in the lighting of the scene.
One easy way for you to improve this is letting the sun hit some of that scene directly, so that your overall terrain has a broader range in lightness. Then optimize the contrast and balance colors for the render in post.
I'm not a big fan of the "2nd sun" recommendation. Global GI should be able to do the job for you, and bear a much more realistic result. You should be ok with 1/2, if you switch supersample pre-pass on. If you want more details in the shadows, go for 2/4, but be prepared for a longer wait.
In general: it's ok if your sky goes white with overexposure. It's also ok if parts of your terrain shadows go black. If you don't make any of these sacrifices, you won't get to the lighting dynamics you need.
Cheers,
Frank
I'm glad to hear the good news but your right, the lightning is always my biggest problem.. I'm not good at selecting sun/atmosphere colors to my scene, and im diffently not good at positioning my sun either, I just place a sun at any random place and then make a test render and if the colors are O.K, well then I stick to it:) I just wan't to take the next step and make it more realistic now..
I'll make the stones smaller, I thought they were too big aswell but it takes me 6 rendering's to make this picture, I crop the picture in 6 pieces and render each one of them..
But you spoke about letting the sun hit directly into my screne, would you do that by placing the sun in the middle of your scene and then increase the elevation so it lighten up the whole scene? (did that make any sense?)
I have now tried to place my sun at different positions with a bright blue color but without much sucess.. My "Dream" is to make a beautiful wintery picture but woaw, the lightning is a true pain in the butt ;)
I have tried to change the GL relative/sample to 2/4 with supersample prepass to see if it looks better :) I'm waiting for the rendering to finish..
ps.
Like this picture: http://www.nwdanet.com/images/phocagallery/frank-gallery/thumbs/phoca_thumb_l_At%20the%20pond_web.jpg the lightning makes it look so realistic.. If I made a picture like that, well... It would look like plastic :P
Frank hits pretty much all the nails regarding your final steps to realism.
I'd like to add another important aspect: scales.
Frank already mentioned how our brain compares images with what we know to be "normal".
In your image the scales are a bit off. The size of the mountains suggest great height and depth in the scene, but the size of the house and trees suggest a much less "deep/smaller" scene.
The scales do not work well together yet.
Together with some improvements on the lighting you should get very close to your goal because this is already a pleasant scene so far.
As you have noticed Frank has, like me, his personal preferences regarding lighting.
I like more softer ambient lighting while Frank loves bright contrasty lighting with darker shadows.
Therefore I like to add a second sun sometimes. Though use it carefully; if you have to use a great strength you probably have to choose another direction of lighting otherwise it will look unnatural anyway.
Frank is totally right about rendering with GI 2/4 gives "best" results, at least most bang for bucks for me.
Rendering with this "always" gives good detailed shadows, so a second sun is unnecessary.
However, it renders significantly slower. Rendering with GI 1/2 + second sun or GI 1/2 + increased GI strength on surfaces (enviro light node) can be an option.
Good luck with your "quest", looking forward to see your next iteration :)
Cheers,
Martin
just my 2 bits worth, loose the car, there's something wrong about the scale and context... :)

As my suggestion was actually to give a second colour tone to the scene and not to do with shadows, is there a way you know of to restrict the area affected by a light?

Good that you remind me of this very old render, which I am not particularly proud of - I shall better do it again or remove it ;)
By the way, this image had the saturation and contrast tweaked in the LAB color space. The lighting was not very dynamic in the raw render.
oh, and one last suggestion to save you time: take the same scene, disbale all the vegetation, disable the water.
Then make a smaller render, like 600x300 or 800x400 for testing your lighting, as you play with the sun position, elevation, contrast, gamma, glow amount etc...
Render at detail 0.4, reduce AA to 2, don't use soft shadows or ray traced atmoshere, but keep the GI setting at least at 1/2 + SSP.
That's sufficient detail for testing the overall lighting, and should be very quick to render.
You can add all the disabled elements for the final render again.
Also, center the lake object to where you want your lake to be, and reduce its radius to that it covers only the visible lake area. That should give your final render a turbo boost, too.
Frank
You are right about the scales, I just noticed it as you mentioned it.... It's amazing how many mistakes I can overlook. I will work on the scales after I have learn how to work with more realistic lightning..
You have both giving nice examples of your personal experience with lightning.. But for me, it's hard to judge where the sun should be placed and what colors to use and... and ... and .... I can continue :)
I can imagine what you guys mean but as soon as I open TG2 its like "Alright...... First, position the sun..... Now what?.... Let's add a bright blue color..... Hm, now the whole picture is blue" hehe, as you can hear, my experience with lightning isn't something to be proud of..
I would like to ask about using colours to a specific scene, as I said ealier, a realistic, wintery atmosphere/lightning is my big wish but so far it seems impossible.. I have tried to place the sun at various positions but all I get is a very, blue picture which removes the green color on the trees and everything.. :)
Would it help if I uploaded my tgd file?
Also, thanks for the advice on the test rendering FrankB!
Cheers,
Mike :)
ps. I used the Alphine Moutain Pack from www.nwdanet.com, I'm also thinking about buying some of the Atmosphere packs, they might be able to help me understand lightning more?
Have you tried reducing the strength of the sun, or maybe using the enviro light. Never used it personally but I think RArcher used it in one of his renders that made it about 3 billion times more realistic by setting it to Ambient Occlusion rather than Global Illumination. I've never tried it in a situation where I've noticed the difference though.
PG, it's worth a try! I actually don't know what Enviro light does... I can figure out it stands for "enviroment light" but I haven't touched it before.. I'll do a test with Global and Ambient to see if it makes any changes, if not, then i'll try change the values (their all on 1)
It would definitely help if you'd upload your tgd for us to see what you are doing. "adding a bright blue color" already sounds suspicious to me ;)
my 2 cents advices : try to put your sun a little bit to the right (you need to have the right mountain shadowed and the left enlightened), and strength like 4.5... oh and soft shadows on can bring nice realism...
check your effects in render and try contrast 0.4
as for the "cold look", did you try an atmo haze density 1 and bluesky density 1 ?
I don't know what your values are right now, but that's what i will try personnally. and i won't try the second sun before being sure i correctly understand how the lighting and atmo work altogether... it's already complicated with one sun so 2 suns... :D
edit : as T-U said, if you post your tgd, i might be able to give it a try too, and "adding a bright blue color" sounds suspicious to me too ^^
I have added the file:)
by the way, don't mind the settings, I did as PG suggested for the test rendering:)
... Don't kill me if I messed it up ;)
It might be better if you remove this file, as it contains (according to you) one of the NWDA Presets, and simply email it to FrankB.
P.S. The scene does definitely have potential.
oh, good idéa O_O Thanks for the reminder Domdib, you saved my butt :)
Well then no-one else can help apart from Frank, which dose raise an interesting question ...

It feels a little strange because I don't want to do anything illegal and get my butt burned if you know what I mean.. This turned out to be a little tricky..
Shearing your file would not be illegal, as far as I can tell ...
:)
Richard
As long as other peoples files aren't attached then it's not illegal. You're sharing your own produce.
you're being funny, guys.
Anyway, it's easy to share the file without any NWDA content, by stripping out the irrelevant parts. Here's one for example. The point is not in the detailed scene elements, it's in the lighting.
Sp34k, you've done quie a few things wrong in your tgd. You have tried to get more blueish light, by making the sunlight blue, effectivly canceling all other colors from the sunlight.
What you want is that GI lights your terrain from the bluesky color. It does this by default, but you can make the GI surface color a little more blueish if you want. See the attached tgd.
Here's a scene that's similar to yours, but just more simplified. Also, you have used a strange color for the bluesky horizon color - not good. I simply added a standard atmo instead.
There are two renders attached. One is the raw output from terragen, the other is the same but slightly postworks with contrast and colors and stuff. The render detail was just 0.4, GI 1/2... but you can see that yourself.

I'm sure your not trying to become the guardians of all things TG, that would be a terrible responsibility.
I would have liked to help (I enjoy helping) but with these protectionist attitudes how is that possible and how dose it help the community, looks like it only helps NWDA members and customers.

@FrankB
Thank you very much for this!:) I have now been studying your TGD file but im still having troubles finding the settings you are refering to.. Like "GI light your terrain from the blyesky color", I don't know all the acronym yet, (feeling slighty stupid)
But I now try and use some of your settings in my scene to see if it adds some better lightning:) I really appreciate the TGD file you have provided along with the finish rendering!:)
Now, I have done a test rendering with some different settings, it looks like the picture I uploaded..
I'm not sure if I did it right but I changed some of my previous values with the ones from the TGD file you provided FrankB.. So far, It's definitely more bright, but I'm not sure if I made the right position for the sun?
ps.
I don't want you guys to argue because of my problems.. I haven't seen anyone argue on the forum before so please, don't make this the first time :) I appreciate all the help people are providing, it's more than I imagined.. But at some point, I can agree with the file I provided being a wrong action because, the NWDA file was included.. Im not sure if it's possible to EXPORT files in TG2 but, I removed it because I don't want to get in trouble with NWDA and their copyright..
Trust me, this isn't the first time people have argued here :D.
I think what Frank meant was simply to use the GI settings that would be right for your scene. relative detail and sample quality of 2 for example and to alter the actual colour of that is used to light your terrain with the bluesky settings in the atmosphere node.
First time I experienced it:P It's never fun to see people argue since it leads to nothing else that negativity..
Anyways, thanks for clearing it out for me :) I'm amazed how much help people are providing.. As you know PG, I'm not the sharpest knife here so i appreciate the "translation" for all the smart TG2 words :)
I'll see what I can do with all the new knowledge i've gathered tonight..!
I've read enough posts here to know that this will be worked out.
It has to be worked out, otherwise I'll have to teach you all some Danish discipline! *evil laughter*
ps. what does "bluesky density"? I see the word "density" alot of places but I havent figure out what it does along with Bluesky additive and redsky decay..
This site is where I learned everything that I know about the atmosphere node. It's really well explained.
http://www.motionmagnetic.com/a_terragen2/atmosphere_examples/atmosphere_examples.html
Oh this looks familary, I remember this site made no sense to me but now I understand what it's about :) Thanks PG, you deserve a kiss on your cheek............. :o
this site helped me a lot too !
Alrighty I have made something like 15 renders with the help from http://www.motionmagnetic.com/a_terragen2/atmosphere_examples/atmosphere_examples.html ..
But I don't think I can hit the BEST spot to make the lightning look realistic on the scene... Maybe there's 1 problem, I keep looking at these prof. pictures like: http://www.planetside.co.uk/gallery/f/tg2/TU-A-Brand-New-Day-Full.jpg.html
And wonder how he/she made the lightning so darn perfect.. Look at the grass, the haze, everything is just so realistic... Maybe that's what is wrong? I keep searching for the perfect lightning to hit my scene so beautifuly people will be like "wow, that's nice made!"..
My current lightning render looks like the one I uploaded, still not impressive I think:P
it's too dark overall. Just crank up the exposure.Do you know how to do that in TG2?
Remember that TU, FrankB and others you mention have been working on TG2 for YEARS, learning the system from its early alpha stages - so don't beat yourself up if you can't emulate them immediately. To really get the best from this program you have to put in the time and effort - but don't forget to have fun!
I think I know how to use the exposure, its the thingy on the left side of the preview rendering? or what its called:P
@domdib, But I want to be as good as FrankB and the others, buhu life is so unfair :'( ... Guess I'll have to keep practicing so I can knock FrankB off his chair 8)
You'll never knock FrankB off his chair, all the time your beavering away trying to get better, guess what so's he!
Might as well give up now :(
Or of course look to others for inspiration but not comparison :)
Richard
I guess your right Richard, but im not giving up :) Ofcourse I know theres a long way to go before I can make anything NEAR what you experienced users makes, but it's not impossible :)
Guess I'll have to make my own style when I learn how to use TG2, let's see what will happen within a year or two..
the learning curve is more like sqrt(log(x)). The growth rate is very limited over time.
So catching up is very possible, as the learning delta is becoming marginal. ;)
Quote from: FrankB on September 03, 2009, 06:16:11 PM
the learning curve is more like sqrt(log(x)). ...
LOL if I knew what that meant :)
... And in English please? ;D
You'll get there. Terragen 3 will put us all on the same plane; if it is a jump like 0.9 to 2 was.
Are they planning a TG3? What about making a 64bit TG2 first?:)
I'm sure they are someday. ;D
No, I was just making a comment about the current users sort of starting out again 'new to the program'.
You can increase/decrease exposure in your camera-node, first setting.
If you work in EXR you don't really have to fiddle with this, because you will save the entire dynamic range of lighting.

I'm using TG2 since december 20th 2006. That's the oldest file I can find :) Unfortunately for me I wasn't member of the alpha team until end of last year, something like that :)
So the head start wasn't there for me at all. Though I used TG0.9x intensively for about 3 years or so before and that helped a lot in developing principles of scene build up regarding composition, lighting, shading etc.
Just to remember you all that with some commitment and determination one can get really nice results.
It was all magic to me as well in the beginning.

That "she" would be me ;) lol
I've attached a reduced version of the tgd which should give you insight on how I did the lighting. You'll see it is nothing really fancy. This was made during my "second sun era" when I had an ultra slow pc and didn't want to render with GI >1/1.
The models and lots of displacements and other confusing stuff have been removed. Take a look at the enviro light, suns and atmosphere node and you should get a fair idea how it's done.
Keep in mind that this setup fits nice for this scene. Hence, I didn't do any postwork at all.
For other scenes it might work not so well. Each image requires its own lighting-setup. In my experience there's no golden-standard for lighting which will always give optimal results.
Cheers,
Martin
(or should I say Martina ;))
I watched Seth and others come in here like him with nothing and they just jumped in and tried stuff and asked questions and learned and did better than not quit. They loved every minute of it. I had a year on them and they surpassed me in execution so I was asking them questions. Everything is relevant, I guess. But, enjoy it. Don't pain about what others might be better at (you know, comparing). It'll come and I hope you'll find fun in it, too.

haha.. Please accept my apologi, I didn't know if the artist was a he/she or fema..... Anyways......
I'm very pleased with the attacted TGD file, tomorrow when I wake up I'll be taking alook at it and learn from it :) I just came home from town so im pretty tired..
But eventhough your lightning may not fit my scene, then I'm sure I'll learn something by looking at your settings.. I appreciate it alot and thank you for sharing it. I look forward to learn from your file :) Much appreciated ma'am.......... :D
@calico - I'm trying to learn as much as possible eventhough I keep looking up the the more experienced users, it's something hard but it's inspiring aswell.. One day, oh one day I'll be in control here on the forum and sharing my wisdom with the younger ones ::) ........ Dreaming is not illegal hehe..

As far as images go, the oldest Terragen 2 file I did was Feb. 2008. I did not really get a handle on the program until May 2009, when I started hitting the forum here. There is still so much too learn...
@Tangled-Universe:
I have your attached TGD file open right now.. Beside being a great scene then I'm facinated by the 2 suns (again) - I never found a functional way of using two suns but in your scene they fit great..
I also learned that, when I used 2 suns I applied shadows on them both and thought it would look more realistic, but I can see you only applied shadows on the strongest sun.. I also never went higher than 4 in sun strenght, while you use the strenght of 6, it's interesting:)
Another thing that I would like to ask about is the "Visible disc" under lightning - sunlight, I haven't used it before. Do you always use Visible Disc? If no - Why not? and if yes - Why?
You also increased the "redsky decay" from 1 - 2, why is that?

Seems you paid quite some attention to my file, nice to hear it is of use to you :)
The reason I only enable shadows in the stronger sun is simply because that is my main lightsource which has to tell the viewer from which direction the light is coming.
The other sun is on the opposite of the main sun, has lower strength and doesn't cast any shadows, just because I want the light from that sun to lighten up the shadows. Otherwise you would have shadows on both sides of an object/terrain and that would look rather unrealistic.
You can increase detail in shadows with higher GI settings, but this scene is very heavy because of the models and the required detail settings of the renderer to get a nice crisp image. The second sun is a simple/crude way of getting lighter shadows. It's essentially a fill light and you'll see in many non-landscape 3D images that people use more than one lightsource up to many even.
At the time I made this image it didn't come to me yet I could use a 2nd enviro light with ambient occlusion enabled (reduced values for strength), which is another way to make shadows lighter.
Visible disc is visible disc, it has a straight-forward meaning. When you render an image with the sun in the middle of your picture and you disable visible disc then you won't see the sun's disc. Simply that.
The reason I increased redsky decay from 1 to 2 was probably because I wanted a slightly more yellowish lighting in my image. When increasing this image you'll "thicken" the atmosphere and thereby the influence of redsky decay will become stronger. Logically you would need a sun elevation which allows you to get that effect.
If you have your sun at an elevation of 45 degrees or higher the influence of the redsky decay is way less than when your sun is set at 20 degrees for example.
I hope this is all a bit more clear now.
More questions? :)
Cheers,
Martin
@Tangled-Univers
The description about using 2 suns has been very useful, I often experience some heavy shadows but using the "2nd sun" to lighten them up is not a bad idéa! - Using 3 suns is maybe too much for me to handle right now, my next project will be using 2 suns :)

Using two Enviro light wont be messing up the picture? So far I haven't found any difference between
Global and
Ambient light.. Is is something I should learn about now or, isnt it that relevant?

In otherwords, it has a better effect if the sun elevation is lower, like a sunset or behind some mountains, then the effect increases?
This helped alot along with the TGD file you shared.. I can't wait to try these things out and see what I can make :) Soon I'll get back to my picture (related to this thread) - and work with my new knowledge about atmoshpere and lightning..
It has totally been worth making this thread, so thank you once again :)
Right now I don't have any questions and even if I did, I wouldnt be asking right now, I have learned alot from this thread and it's time to test my knowledge before moving on:)
*Edit*I have done a new render after playing with the lightning, I need some hornest, hard and no-mercy response to what I could do better..
I rendered this test with:
Quality: 0.7
AA: 5
GL: 2/4
Supersample prepass: ON
New lightning: www.sp34k.com/ps/lightning_new_render.bmp
Old lightning: www.sp34k.com/ps
