Maya version of this 3ds Vray cloud shader?

#1

I’m trying to create a cloud shader exactly like this one:

http://vray.info/tutorials/vrayenvfogclouds/

but for maya. For the life of me, I can’t figure it out. I’ve tried all sorts of 3d-projections. The closest I get is with a solid fractal which gives me the individual blobs, but they’re perfectly round and I can’t figure out a way to distort them. One would think the Cloud node would be perfect for making CLOUDS, but no it seems to be the worst option.

If anyone can offer a way to get the same result in the link above, it would be super appreciated.

I’m sure the technique can be applied. Not sure if Maya’s noise can produce similar results tho. The way you apply vray fog in Maya is a little different. First you give your polygon a vray shader. Reduce the material’s opacity to 0. Then you go to that shader’s shading group and add vray environmental fog to the volume slot. You could probably plug a 3D noise into the fog’s density and see what happens.

Thanks for the reply. I probably should have explained my setup. I have a default mtl with 0 opacity for the surface material and the environment mtl plugged into the volume slot. I then have a volumetric noise with “alpha as luminance” checked, in the density.

The best i can do is this:
Left is a short cube 100x10x100, Right is a sphere radius of 50

I dont seem to have any control over seperating the clumps without losing the irregular shapes. Any ideas?
