Well, my question is how do you make clouds in the sky. Particularly, thin whispy clouds. You don't use volumetrics, do you? A tutorial would be great! Thanks!

something I picked up and messed with on materials. Just play with the numbers??
Then add the material to any shape patch.
SPACE SCENE MATERIAL SETTINGS
Cellturb - B/W
Cellturb:
Translate 0 0 0
Scale 50 35 25
Amplitude 100%
CellularNoise - Rounder
Threshold 10
Octaves 2
Point Density 100
Euclidean off
Attributes 1&2 B/W (nothing else)
-----------------------------------------------
Sky
Fractal Sum - Blue/White
X - 4000 even up to 10,000
Y - 2000
Z - 6000
Amplitude 100% Changes sparsness of clouds *40% Up to 300%
Octaves - 1->5 (Changes size of clouds)

Is each one a different texture, also a pic would be cool, also, what type of material did you start with, spherical or gradient?

Sorry to jump in on Darkwings topic,I have a need for Volumetric clouds on my project and a while ago I'm sure i saw somewhere that someone had created
such an effect.If anyone knows what direction to point me in i would be eternally grateful.

If you create some little whispy clouds in an image editor on a transparent background and save them as 32 bit Targas or PNG files you can use them as sprites to generate clouds. Set one or more sprite emmitters to fill an area with cloud particles prior to the frame that you will start rendering from. You can then blow them across your sky with forces.
Well, that's one way of doing it anyway.

Thanks, I like Johnl3d's clouds, how did you make them?

It really an animated material. Did you try downloading the project ? I might have an updated version....

Don't mean to sound rude, but, what does it all mean? The HTML that is

Well it's scripting or something that I couldn't understand. It was all a bunch of code or something, I don't know if that's the way it's supposed to be.

Actually all I did was animate a material...I'll have to put together a tut ..maybe this weekend if I don't get any surprises

I figured it out, my computer was reading it as an HTML document, so it kept opening with the internet, but once I used AM and opened it that way, it worked. The Styalized cloud is the only that I'm not 100% sure about. The two layers are just the same in the chor, right?

Yes..if I remember I did that quite awhile ago

I tried reproducing the stylized clouds, but it didn't turn out quite right. For one, it doesn't move, and another is that if you open up the material editor on yours, there's like circular rings, but when I did mine, it was too, well, I can't describe it. The only thing that I can think of is that you had a driver on the model, but I don't know how to do that.
