adding noise to shader? Aug. 14, 2010, 3:20 a.m.

I want to add a noise to constant smoke shader. How can I do that?
Once that is achieved, I want the noise to change with time and move in object space so that the moving object will appear like real smoke. Any ideas??

billowy smoke shader noise moving as the object moves? Aug. 12, 2010, 10:41 p.m.

I have been looking for cloud rendering. If you could show me a simple example of how to break a volume render with noise that would be great.
thanks,

billowy smoke shader noise moving as the object moves? Aug. 12, 2010, 8:01 p.m.

I am attaching the file with the changes. Basically I want to render particles as clouds. So I am attaching an isoOffset node to platonic objects, adding a rest node and copying to the particles. I am applying a default billowy_smokeShader to the copied geometry.
The only changes I have made to the shader is inside:

shop->billowy_smoke->billowy_smoke->if_densityNotZero->restpos1

where I specify ‘Space’ to ‘object’.

Is this the right way to do it? Do you know a better way to render particles as clouds? I have to render a tornado of particles eventually.
thanks,
