VRayEnvironmentFog to only show where lights are?

[Morne]

Hi all

OK so I need the VRayEnvironmentFog to just be VRayFog if that is possible? In other words I only want fog in the beam of my light. Kinda like Volumetric lights work in max with scanline and standard lights.

Is this at all possible?

anybody have a clue?

You can use a cylindrical or conical gizmo to limit the volume effect just within the light cone.

for now I'm using it as is because my situation is a bit more complicated. I have a rectangular light shining through a complex "slot".
Using more or less defaults with the distance tweaked a bit, is actually working not too bad...

Maybe I would use your cylindrical suggestion to make aircraft search lights
