Ok, I was looking at my Fire demon and something about it, as cool as it was, felt /off/ to me. After thinking about it, and looking at some other threads, I realized what the problem was. The flames didn't look to be producing any light! A little work later, and here is the Fire demon again, now with what I hope works as object sourced lighting.. I think that's what the effect's called!
C&C's as always greatly appreciated.
