Description

Compressed one channel (R) texture format.

BC4 format compresses textures to 4 bits per pixel, keeping only the red color channel. It is widely supported on PC and console platforms.

It is a good format to compress single-channel textures like heightfields or masks. For two channel textures, see BC5.

Additional resources: Texture2D.format, texture assets.
