Definition

  • Type: Field
  • Namespace: UnityEngine
  • Assembly: UnityEngine.CoreModule
BC4 = 26

Remarks

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 TextureFormat.BC5.
