Say for an average image with maybe a cyclorama background, V3 and M3, 2 or 3 props. I use P5 and have 1 gig of ddr ram and as yet have not had the dreaded "out of memory" warning but I've heard a lot of people say they have. Is there a general relationship between the size of a Poser file and how much memory Poser needs to complete a render? Thanks 8) Catlin
