Blender is eating GB's of HD space when rendering. Its uses up around 5GB for a few hundred frames of animation and doesn't release it after its finished. I gather this may have been because I had cache BVH ticked.

I'm on osx 10.9 but can't for the life of me find any BVH files? How do i find them on a Mac, or is my problem elsewhere?

  • $\begingroup$ It usually does this when working with physics/particles etc. And yes, it doesn't release(Read delete) the cache afterwards. There is only one workaround to it. use specific area of hd for cache and delete it after usage. A system with 1000k particles, or fluid with 96 res can easily take up 5 gb of space $\endgroup$ – Ali Jibran May 13 '14 at 19:40

The bvh cache files can be found in a folder called cache that will be located in the same folder as the config folder that contains startup.blend, the filenames start with bvh_ followed by a unique 32 character string.

See this page for details about where the config folder can be found.

This question has more info on when the BVH Cache can be helpful.
