One thing I do is 1) Save a lot before rendering and 2) Shut poser down if I've been playing with texture maps. I shut it down and then load the biggest memory hog of a program I can think of, usually "mame" running Mortal Kombat. (emulators eat memory like crazy). Then when I go back to poser, the memory is cleared up properly and extra tex maps are no longer in memory or in the pz3. Frustrating nonetheless. -Darth
