Smoke simulator memory leak with high poly mesh emitter
Closed, ResolvedPublic


System Information
Windows 7 x64

Blender Version
Broken: Official Release
Worked: It appears to work with an older 2.69.3 build.

Short description of error
If you have a highly subdivided plane used as smoke emitter memory consumption will go up steadily even with a low res smoke domain. Also memory isn't freed when loading a new scene.

Exact steps for others to reproduce the error
The attached .blend file has such a setup, just press Alt+A and check the memory usage. At frame 200 it's at around 3,5 gb on my system, at frame 300 at 5,2 gb and so on.

i think i found the cause of this memoryleak. A copied derivedmesh was not freed after usage and copied again and again....

See the patch file for a (possible) fix.
