Call System Eyes at (603)424-1188. The meetings are the second Tuesday of each
month. I attend when I can. I was planning on showing up on Tuesday to show
a really spiffy logo animation I just completed for our company (its 42 seconds
long), and beta copies of Impact and FiberFactory. This meeting is in 2 days.

By recessing your flare source into your reflector object, enabling fade
behind object, and making the object a shadow caster, you will get a very
basic attenuation. The flare will fade quickly as the reflector obscures
the source. In the logo sequence I just mentioned, I have a series of
rotating lights which use this technique, and although it is not perfectly
accurate, it looks pretty good.
