Fog

[dangerweenie]

Hey Vlado,

Sounds good, but I'm having a hard time confining the fog to an area!

So what is the proper shading network to use when you want to assign an environment fog to a piece of geo (like a cube or a sphere as a bounding volume) for the fog effect? And when you do it this way, do you need to plug anything into the environment fog slot in the v-ray for maya render globals?

Thanks!

You can use the standard Maya way, and assign a volume material to the geometry. Or you can use global environment fog and assign meshes to it (it's a set).

Here is an example with VRaySun and GI

ah! I was trying to apply it as a shader - this scene is very helpful. Thanks so much!

arghhh.... Couldnt get it to work..
Had to untick cast/recieve/primary visibilty on the meshs shape node.

yes, you need to untick those in order to see the EnvironmentFog effect

Hello, nice scene bazuka!
I was wondering how to achieve a texture to the fog material, to make it more "cloud like". I have been plugging in 2D/3D textures to the density but to no effect.
Any ideas (without having to use fluids/containers)?
