On second thought, I will repeat my complaint that point lights DO NOT WORK with
atmospheric media. This is either a bug or a design flaw.
I wanted the effect of a light bulb inside a wiffle ball in the fog. I set up a
porous object (based on 3d noise), but a point light inside, and had NO effect. I
removed my porous object. There was still no effect. Thus, I conclude that point
lights do not interact with atmospheric media.
