I never had this problem with PPP, but in P6 it doesn't seem to matter where I place the lights, I always get a shadow from an upfront object, if there's one there, as if the light were facing head-on down the Z axis. I can put all the lights down the Z axis pointing even behind the object, and still I get that shadow - from the front. I have the SP 2 installed, too. Is that a bug, am I missing something obvious? Or has Poser 6 created its own new laws of physics without telling me?
