Wow!  Great responses.  Thank you.  This is helpful.  I won't worry about the falloff possibly complicating my efforts, then.  :lol:

BB, I have IDL enabled, but not GC.  I have enough frequent use shaders which have defied GC conversion that I've stopped thinking seriously about moving into GC at all, at this point.  :sad:  And... basically I'm not using GC because my shaders aren't "correct".  I lack the skills and know how to do more than arrive at something that looks more or less like I want.  My understanding of the physics and math involved in making correct shaders is haphazard at best.  As evidence, I submit the fact that I had to ask the question about inverse square light falloff in the first place.  :lol: 

seachnasaigh, using proxy meshes for the effect I want sounds like a pretty good idea.  I'll see what I can work out.  :thumbupboth:
