Memory Problems

[samuel_bubat]

Hi there,

I have a quite big scene to handle.
When I open the scene it uses around 600mb of virtual Memory.
When I hit render the virtual memory goes up to 1,2gb during loading bitmaps
and compiling geometry (goes up to 1,8gb including lightcache and irr. map).
After the rendering is finished the virtual memory usage does not go below 1,2gb again. Looks like it keeps all the bitmaps and maybe geometry in
the virtual memory. This causes the second rendering to be much faster
(nearly no loading time on geometry and textures). However, after the rendering is finished my viewports are extremly slow and I can hear my harddrive swap. I have to close and reopen the scene again to get back
an acceptable workflow speed.
It would be great to have an option that clears the virtual memory after rendering !!

samuel,
Have you tried turning on the max bitmap pager?

customise/preferences/rendering/ and turn the bitmap pager on.

Hopefully that helps!

There is a maxscript command to flush all textures out of memory:

freeSceneBitmaps()

VRay used to flush bitmaps automatically, but since some users complained, it was reverted to comply with the way the scanline renderer works.

Best regars,
Vlado

vlado, could this be added in the system rollout as an option?

Thank You very much.
Works now with that little maxscript command. !!
