.umbracache and .info files

Unity Engine
1

Hey all…

I have a HUGE number of .umbrachache and .info files. Can these be deleted and will Unity regenerate the ones that are needed? Curious to know how many of these files are out of date and which are truly needed.

I realize the ones in the occlusion folder will need to probably get re-created manually by occlusion baking.

After looking more into the Library folder, I see a bunch of .bin files in the ShaderCache folder.

Is it ok to just completely clear out the Library folder from time to time and and allow Unity to recreate these files as needed?

Thanks

I have the same problem. Did you manage to solve it?

Ugh, I dunno. That was a long time ago. :slight_smile:

It’s OK to delete the Library folder. Unity will regenerate it when you open the project next time. Make a back up first, of course.

More than 200 thousand “.umbracache” of 1KB size ，maybe my map is too large.

Given the read speeds of modern drives (SSD/NVME) is optimal around the 32kb and often the default NTFS file size is greater than 1K then not only can these files waste a lot of space they are very slow.

Amazed a simple filesize optimisation is not applied to .umbracache files e.g. min 32 kb max 64 kb?
