Is there a way that I can control the volume properties per lamp?
I want to create beams of light that are visible (no problem with that). But to fill in some parts I'd like to use an second light, that lit's the object without being visible in a volume.
I formerly used Maya for stage design and within Maya you can assign the amount of interaction with the volume per light.
Attached a picture to clarify my problem. In this image there is a beam that I want to be visible. On the other hand, I don't want to see the volume of the area light.
