omg double rainbow!!!!!
what does it mean?....I mean how did you do it?
looks great
Rainbow looks impressive. The grass shader isn't really designed for close-ups though, so either lifting the viewpoint some, or distance shading in a grass object population would give it a more authentic look.
Amazing!!
Though it's a little small, rainbows have a 42º radius for the primary bow
If this is procedural, it's really a great achievement. There is some banding; can you get that any smoother? Care to enlighten us about your method?
Thanks for all your comments.
@ Inkydigit :
It means that I passed not only that storm but also the written part of my final exams
-and how I did it I will tell you later.
@Dombib:
Actually I didn´t care for the terrain that much in this first version, just wanted to show off my rainbow ;)
@mesocyclone:
of course you are right about the angle, the second bow is also to close, but I wanted to have it all in the image.
@Dune:
Yes, the banding is a problem. unfortunately my preview-cropregion was in the righthand part where it is least obvious.
I am sure it can be smoothened somehow, but that will need some finetuning.
What I really don´t understand is why the violet part appears so low, it even looks unconcentric, what shouldn´t be possible.
Could be foreshortening, but I still don´t understand it.
I will share my method and a clipfile, but my ego would like some more comments before I do so. ;)
Best regards,
Jan
Wow! How did you create that rainbow?
(copy, paste, and post the above text to fast track solution) ;D

Ah ha! I think I see what you've done here, very good! More altitude in the colours(from a single radius control, I would think ???) and push it way back in the distance and you're onto a real winner! 8)
Congrat's on the pass. Twice! :)
*Edit: TBH, the colours in Jan's rainbow are reversed in the secondary arc. Unless I've missed a previous version edit. ???
I'm not sure how you've done this outside post work. Intrigued.
Thanks Schmeerlap,
your kind words show me that you would like to see my clipfile. ;)
Blackhole, look again, there is only one version of this image yet and the colours are in order. Although I have learned since that secondary spectra differ in some other ways, but anyone can adjust his rainbow as he likes, so I won´t change much now.
dandelO, Thanks for the congrats.
I am not surprised that you get the clue, maybe I would have tried it with a bunch of spherical distance shaders if I had not seen your metaclouds, that would have been a pain.
So, I used one planets atmosphere with 14 cloud layers.
Funny thing is, I thought I would have to use the intersection of this sphere with two linear distance shaders to cut a slice out of it, but I realized that those shaders weren´t plugged in only after it looked like it does.
There is only a diffuse shimmering of colours that shows it is a sphere, not an arc, and I think the sphere-shape helps blurring the banding, at least where the density is high enough.
I am working on a second version now that I will post tommorow together with a clip file.
But I still dont understand why the violet arc seems to be flatter than the others.
Maybe it is foreshortening and will be solved if the whole thing is bigger and further away like dandelo suggested.
Thanks for your interest,
Best Regards,
Jan
I had an idea to restrict an atmosphere, like I did with the Saturn ring image called 'the grudge', I posted a while ago, but I can't find a way to constrain an atmosphere node in that way. I don't think it's possible.
I can make a perfect spectrum with one atmosphere node BUT it can't be constrained to a ring conventionally(ignore the red/yellow object in the centre, when it isn't rendered, the colours are correct).

Alas! I didn't go as far as 14 cloud layers! Cool! :D
It would be seven cloud layers for a single rainbow, and I wonder if your method could work together with mine.
As I said, these spherical cloudlayers arent restricted at all, I wanted to but didn´t by accident.
They are only that thin that they only show up much where you look tangentially to the sphere.
Maybe that explains, what is flubbergasting me at the moment.
It seems that how ever I move the rainbow-planet up and down, (even to the sides) the rainbow stays the same. That makes no sense, there must be a mistake.
For one moment I thought it may really move with the suns counterpoint, but that doesn´t work either.
Test renders are slow on my computer, I think I will just post the TGD in some minutes.
Correction, it seems to be broken.
Let me fiddle with it some more, her comes the beta version of the clipfile, it works if simply thrown into the landscape, but there are some things that I still don´t understand about it. Have fun! I think I will make a better version soon, but maybe it´s just like with the starfields, once the idea is there evolution starts.
Best regards, Jan
I don´t understand it!
Maybe the same thing as in this thread is like what you are experiencing with the rainbow not being able to be moved... http://forums.planetside.co.uk/index.php?topic=10667.msg109805#msg109805

What was the grass made on? Blender?
QuoteWhat was the grass made on? Blender?
Terragen 2. It's not really great this close up. :-[ :D (http://forums.planetside.co.uk/index.php?topic=10783.0)
I didn't know you could make grass on Terragen 2!
Yes dandelO , that link is enlightening to, thanks again!
I think the violet cloud layer was for some reason the only that moved with the planet, therefore slightly to low after a littel adjustment.
And totally off after some more.
cbest,
here you go, all the laurels go to dandelO!

By the way, there haven´t been so many rainbows in TG either, though I have to admit that there where some.
I will go to bed now,
Its three in the morning here.
Good night!
QuoteBy the way, there haven´t been so many rainbows in TG either, though I have to admit that there where some.
Ah! But you've made the new drag-and-drop one, that no one ever has! :)
I've downloaded your tgc, but not dissected yet. Thanks a lot. But, just thinking aloud; wouldn't it be possible to color just one cloud layer by a blue node configuration? On the other hand, that might be just as complicated...
Dune,
I thought about that to, and I think dandelO at least got close to making a rainbow that way. I bet it is possible.
But I like my variant, I could simply switch of yellow in the outer rainbow or whatever.And it is my own method, the kindergarden-crayon method maybe, but the results are ok imho.
If I can get rid of the banding, what I am trying to do now that the other mysteries are solved, I am fine with it.
Of course one cloud layer would be more elegant, but I don´t know how to do it.
Make yourself at home with InstaGlow Forcefields to go!

I don´t know, at the moment I got a headful of ideas but not the patience to go into details,
that atmosphere bug that makes my rainbow to go unmovable also took the wind out of my sails.
I just played around wih the "rainbow" a bit and built this scene around it.
I really like the effect, but it is a pain to "work" with as long as the atmosphere doesn´t move with its planet.

Talking about astrophysics, what do you think of my rainbow-spheres?

:D
Jan, thank you for the file. The more minds we have working here the greater the possibility of resolving the issues that remain. I'll try working with it and report back if I discover anything new and worthy.
amazing InstaGlow Forcefield! that will be useful someday :D
I like the force fields. I've made a purple one that surrounds the default planet.
I've spoken with Jan about this a while back, what I have found is that each cloud layer that appears further down the node tree than the FINAL one, that plugs into the planet, will not move with the planet translation. Only the last layer moves.
The only way I have found around it is to first move the planet then, visiting each cloud layer that feeds it, systematically plug each one directly into the planet node. This resets each cloud's coord's to the position of the planet and then you have all of them in the correct location, you can then link them up again in series.
The problem is, if you move it again, still, only the final layer moves with it. You have to re-plug in each cloud layer to the planet to reset their coord's.
This way, it can be moved anywhere but, it takes a lot more time than it should, when you have to manually reset each layer to the planet coordinates. I've not come across a way yet to pull around multiple cloud layers with a single planet handle. One layer can be moved around fine(which is why Jan's bow has the final layer closest to the planet, apparently, off-centre, when actually, it's all the other layers above it in the network that are out of sync). It's a shame it needs all this replugging at each planet translation but, it can be moved anywhere.
I haven't downloaded the clip but a good primary bow can be made from 4 layers; red/yellow/green/blue with blending cloud altitudes creating the colour transitions(e.g. red mixed with yellow creates the orange band so it isn't necessary, etc...). A secondary bow could take this to 8 nodes, instead of the 14, I think was used in this file.
That's if it can indeed only come down to re-plugging each layer to reset its position, the less nodes to plug in each time, the better. It's a great technique but a clumsy transform control. I'll post back if I find a way to move everything at once, although, I think it's not possible just now.
Not even if you put the line of nodes into the interior of one final 'handler node'?
Thanks dandelO for explaining it here,
I somehow thought it was already somewhere.
Dune, tell me how to create a handler node and I´ll try it. I have no idea where to look.
If it works this would be a great inclusion to my update, which is meant to include more realistic proportions and a real restriction to a ring, because in many settings the "forcefield-effect" gets quite strong.
Thats what I like about TG, you can use a piece of someone elses work, go on with it and create something new.
Of course this is true of all artforms, but here it feels more like cooperation than plagiarism.
Therefore I hope to make my rainbow more useful.
Best regards,
Jan
my first animation, sorry for the low detail.

Ah, damn, flickr makes a jpg of my animated gif.
Put it through Blender. Blender can encode video in any format you have the codec for.
Its more a problem of uploading than of encoding. I think.
Can anyone tell me the best way of loading a short animation (22images) up to this forum?
I use Vimeo (http://vimeo.com/)for everything.
If its a very short anim try adding a sec of black to the front and back of the anim.
:)

Imageshack hosts .gif fine.
ok, thanks.
I am just trying to make it small enough for an attachment, the quality is really low anyway.
There it is!
click it, it moves.
QuoteDune, tell me how to create a handler node and I´ll try it.
It's just any node (surface shader or color adjust shader...) If you have your stream of nodes, copy them all, then right click on this 'handler' choose 'internal' and you'll get an empty page. Paste your nodes there. Go one level up again, and then attach the last of the internal nodes to whatever input you want. A plus sign on the node will tell you it has things inside. Maybe this could help. I hope I told you clear enough.
Thanks Dune, I will try that!
Good idea but, as it's made from cloud layers, container nodes won't work, even putting all the layers inside the last cloud layer doesn't work. It's a tricky one.
What a pity, so still no rainbow to go.
dandelO, you are to fast ! ;)
But have you noticed my great HD-animation by the way?
At least the rainbow can be easily restricted to an arc now, forcefields only for those who need them.
