Faking a Volume Light effect in a glass cube with volume fog
show user profile  Higgenbotham

Is there a good way to simulate a volume fog effect (need not be perfect)? I'm using Max 9 with mental ray rendering. The scene has a projector inside a glass cube, with a volume fog effect inside the box. I tried making a cone and applying a transparent raytrace shader with an IOR of 1 and a map plugged into the fog color slot. This looks fine but is doing strange things with the volume fog and light reflections inside the glass box. Any ideas on this one? How do I upload an image so that the problem is more clear?

Well Hig,

Can I suggest a Glow (lume) shader type with a transparency base map in the surface material slot, and for the transparency map settings, a radial gradient map, which controls the opacity of the cone and fakes attenuation. Hope this helps you, -H
