Here I am again with another stupid question. XD What's with the rings of light first of all? They always show up in every render I do. And as for the mysterious black holes magically appear on certain terrain props that I have when I do more advanced renders. How do those appear? One more question. Is it a Windows Vista thing? I have poser 6 on my other computer with the Windows XP operating system and have never had this happen. Does anyone know what all of this is about and how to fix it?
