I forgot to mention the little detail about the s-cams' inconsistent naming behavior when changing light names and adding new lights. It gets to be a confusing mess real fast, unless you keep up with the renaming. The various companies which have published Poser have failed miserably at informing the users about this undocumented feature. I wish somebody knowledgable about the entire spectrum of details on the shadow-cams would divulge the secrets of poser lights and shadows. I have only scratched the surface, but what I have learned has gone a long way in speeding up the time it takes to get the render looking how I want.
