Ok, that explains why all the RDNA lights work for me-- but not why the Evodes lights work -- those were the first I switched to from Poser 5, and the Marfono lights work, and Blue Venus, Spanki's, TheUmbra etc and so on. Could it be that renaming ones lights is a dangerous thing to do in Poser? The only sets I haven't tried are the the sets form PoserStyle becuase they were getting consistent freezes in the the old Beta forum. The worst thing about the bugs in Poser, imo, is the randomness of their occurrence. Just started up after takingtime off to heal a sprained hand and it's as if I'd defrag'd my HD, just installed Poser 5-- no freezes and lightning fast Firefly renders. I know it won't last, I just don't know why it's working so well now. Emily
