Too bad 3D Studio doesnt have a feature like Word Perfect has, where you can arrange that the "save function" happens at whatever interval you want.. every few minutes or whatever.. But to return to the problem of that PHar lap notice.. why is it that when I render to the screen a .tga drawing i'm working on, it goes up by 3 megs each time until it gets to the max ram I have of 16 meg (available says 14,000 available) 2 then 4 then 7 then 9 etc.. till 14 then it starts to page to disk.. that I understand is basically a lack of Ram … But why if I go into keyframer, give it say 30 frames (.tga) and render to disk they go up to about 9 megs and stay there…Why does one chew all my ram so fast and the other stabilize after a few megs?
