My P7 is still on the CD. I know that in P6, once you exceed your memory, a texture (skin, etc) gets dumped off and you cannot reload it until you reboot. Mostly to free up some memory again. I'm guessing! ...but, perhaps "secondary" textures(bumpmaps) get dumped instead in P7 so, to not lose the render..but to free up memory. They said "better mewmory management" in P7 yet, it has to come from somewhere. You need stewer. Do you know him?
