Channel Packing
Channel packing is a game art term for a bitmap that has different grayscale images in each of its channels... Red, Green, and Blue. Alpha can also be used as a fourth channel. This saves memory, but increases complexity.
Compression Artifacts
If you save a channel-packed texture using DXT compression, it will introduce blocky artifacts to your channels. For details, see NormalMap#Normal_Map_Compression.
