Ok lowering the bucket size to 15, and hiding everything you cannot see seems to have helped. I just put in a new light and was able to render it again. This is one of those times when I really wish I had the low res mike and vicky figures. It still takes it 5-6 times as long to render as the old P4 engine does but that is acceptable for the moment. I still have 3 characters and clothing that need to be added in but at least now it isn't locking up. I dread trying to do hair, as the hair always seems to lock it up.
