Fog Shader

[fatema]

Hello,

I am creating a scene with rolling fog going through an alleyway. I need to know if anyone has a cool fog shader for this procedure for Houdini.

Thanks,

Fatema

Thanks I just saw that. I'll play around with the attributes and hopefully it will work fine.

Mmmm, before using 3d textures i would try to use a simple volumetric light with Z maps, maybe it would be enough.

If you nedd more control, for example you wnt to use a particle sistem for the fog the you should use 3d textures, see altbighead post, or point clouds.

But if you only need a simple fog effect with a little of noise in the fog i think that a volumetric light can do the work.

Yeah, I am using a particle system. What do you mean by altbighead post?
