Is there any way to specify where Blender saves the BVH cache files? It seems that it always goes to a folder inside my user profile (in my case, on Win7:
c:\Users\username\AppData\Roaming\Blender Foundation\2.70\cache). I frequently run into system warnings and slow performance because the BVH cache files quickly fill up the available free space on that partition (almost 10 gig). I've got plenty of room on other drives but I cannot find a way to change the cache location...
Is that a bug?
Related: Is caching BVHs also useful for scenes where animated characters are acting in a static environment? The status text at the top of the render view does not indicate that Blender is rebuilding the BVHs for every frame (it only says "Updating BVH for scene" - but this takes far less time than the building for the first frame). So I guess this means it's working as intended but why is it creating upwards of 5 gigs of cache even for relatively simple scenes?
