A few days ago I saw Poser eat up about 400 megs when I did a close-up with the Noa tex and a bumb map. But after the render, Poser returned everything to the OS. The second render I tried just froze, and Poser had only used about 140 megs at that moment. I just don't like having to save those pz3 files, just because Poser is about to freeze. And then having to quit Poser and restarting it, just so it can freeze again after 2 or 3 renders.
