This performs a compression step for textures that have the VRAM Compressed, VRAM Uncompressed and Basis Universal compression modes. This usually reduces file size for each compressed texture by a factor of 2, without affecting the memory taken by the texture after it's loaded. This can make for significantly smaller PCK sizes and therefore faster downloads. Additionally, for image pixel formats that cannot be VRAM-compressed (such as HDR + alpha), this allows having some form of storage compression to reduce file size by a potentially much larger factor. This can be disabled in the Project Settings if having the fastest possible import/load times is desired, at the cost of larger PCK sizes.

Some backwards-compatibility system should probably be backported to 4.4 (maybe 4.3 also?) for reading disk-compressed textures, or at least throwing an error when encountering one. Currently, many compressed textures load properly, but are visually corrupted due to using the raw data |
