V-Ray V-Ray for Maya General

does anyone know , How do I get a spot light or any light to emit a volumetric fog , like you would get for example coming through a backlit forest?

Thanks

Hi Chris,

you can use some geometry (like a cube) to contain the fog. Then attach the VrayScater into the volume material of the geometry.
Any light within the geometry will appear in the fog and any geometry will cast shadows.

I have sample file but I can’t attach it. DO you want me to email it to you?
