Can you show me the setup of what you're trying to do? I don't want to go on a long explanation of why you're going about the lighting the wrong way unless you really are.

Are you doing indoor or outdoor? Day or night? Do you have objects in every direction (a room) or are substantial parts of the world empty? Which version of Poser are you using? Have you dealt with gamma properly? If P8 or PP 2010 are you using IDL correctly?

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
