wich node allow to twist/warp Clouds Layer
« on: October 17, 2018, 04:16:03 AM »
Hi all, I'm testing some clouds, very simple for now, in the images you can see a top view of a storm, to create that i simply stack 6 Cloud layer v3 with different Density fractal, my question is which node allow me to warp or twist an entire Cloud layer on a specific axe (like following the red arrows) to give the wind motion feeling?
Cheers

Have you tried the vortex warp shader?

It's a pretty handy shader, though I haven't created a nice storm yet, I've tried. Hope you can create something epic. Good luck.

You an access it via the Node Palette (N), or the Right Click Node Network -> Create Shader -> Transform/Warp Shader -> Vortex Warp

You can stretch the Y in the original cloud fractal, or use a transform shader to stretch Y. Should also be possible to warp a cloud fractal and use a vector displacement shader to stretch Y by mask.

Thanks Dune, I did not try to use vector displacement shader yet, will test it soon.

Use a Simple Shape Shader, and position it where you want, with the radius you set to Circular instead of square and simply mask you  Density Fractal shaders (inverted).
