Thanks for the answers.  :)

The Room of Light looks interesting, but I notice it's Poser 6 & 7 and I'm running 8.  I know there were some changes done to the way lighting works in 8.  Maybe I'll contact the merchant to see if this will work in 8 too.  It seems to do nearly the same thing.

From what I've seen, I know some work in layers and postwork some of the Effects in, too.  One of my new favorites has a great green swirly atmosphere that's postwork.
