Question by joxdev_pavel_glagolev · Dec 30, 2021 at 11:35 AM · graphics texture2d compression

Crunch compressed textures are not supported with CopyTexture

When I try to copy from entire crunched compressed texture (ETC2) with Graphics.CopyTexture, a runtime error occurs:

Crunch compressed textures are not supported with CopyTexture. The destination asset's CPU data will be corrupted.
Graphics.CopyTexture could not find destination GL texture object. Maybe it is a RenderTexture that is not created yet?

What is the reason for this? As far as I know, crunch textures are uncompressed on the CPU before it loads to GPU. Graphics.CopyTexture should run on GPU. The source and the dest textures are marked as unreadable.

Is there a way to avoid this?
