How to Disable or Limit Texture Cache in Isaac Sim?

Hi everyone,

I am running large-scale data rendering in Isaac Sim, which involves loading a huge number of different assets. Over time, the storage used by ~/.cache/ov/texturecache keeps growing rapidly and eventually fills up my disk.

I want to disable the texture cache, or at least limit its size or location. I tried deleting the ~/.cache/ov/texturecache folder periodically during execution, but Isaac Sim then throws errors saying it can’t find or access the cache: “[Error] [gpu.foundation.plugin] Failed to read texture cache file /root/.cache/ov/texturecache/normal_101_1_0_1758771833_5155999_6.ovtex.0“.

Is there any way to permanently disable the texture cache, or to set a size limit, or to make Isaac Sim handle missing cache folders gracefully? Are there any environment variables, config files, or command-line options for this?

Any advice would be greatly appreciated. Thanks!

You should be able to just delete the cache folder anytime you want. I regularly do it. I delete the whole OV/Cache folder.

You do not want to disable cache, that would be extremely bad for loading files. It would mean that you have to reload textures, over and over again for everything. Just keep an eye on it and flush it once in a while.
