Wave Clouds
« on: March 16, 2017, 12:10:28 PM »
Hello, people of Terragen.

Do someone on this forum has made this kind of cloud? I'm referring to Altocumulus undulatus or Wave clouds like the clouds that you see in a clear sky and dry air after a storm or a cold front. Two pictures of these clouds in attachment. I tried to create this cloud but my renders are wrong. Am i making errors or what else?
Thanks for your reply.
Best regards.

Claudio

Try a long Simple Shape Shader (un-check Apply edge colour and set Edge profile to about 80% smooth step) plugged into a Shader Array plugged into a Fractal Warp Shader as your mask for a cloud fractal.
Play with the settings and you should have something very similar to your samples.
Hope this helps

Or an get postion in texture, X to scalar, sinus fuction, and some warp.

Hi guys,

Many thanks to all.
This is my simple test for Wave Clouds. More works to come but for now i'm satisfied for the results.

Regards and see my pics and file.tgd attached.

Try this setup, it's easy. You can use the transform shader to rotate the clouds to your desire.

I think that warping the SSS would alow for the effect like in the top pictures! But I don't know how do do it...

Another good idea.

I'll try it soon.

Here is an example based on Cyphyr's shader array suggestion (at least as I understood it  :))
A few rocks and water added. Not perfect but lots of variations available with the size, roughness, and warp amount of the fractal warp. Also lots of variation by changing the spacing value in shader array and the proportions of the starting simple shape.

I'm working on several projects but Mars is coming along nicely. I've put some of the latest renders in the image sharing section. :)
