I think you are on to the problem Bog I only have a 1 gig of ram and V4P will pop up a window on very large scenes that I want to render in large sizes and say something like this render will require 873g of ram and you have to click ok before it will start any rendering so the program has been modified in my version to at least recognize the situation. 2 gigs should be plenty however as you mentioned Poser can really raise that requirement a lot. My next machine I am going to shoot for at least 5 gigs of ram to avoid some of these limitations. All problems with the program interest me as I am still testing it so thank you for bring this up. Regards.
