An optional channel of image date in a texture file that can be used as a Transparency map, Height map, specular map, etc.

The alpha channel is usually 8 bits per pixel (256 colors), though certain file formats support different bit depths.

-An optional channel in the texture file that usually defines the transparency of the texture’s [[Pixel|pixels]], but can also be used for other things like a [[HeightMap|height map]] or grey-scale [[Specular|specular map]]. The alpha can be anywhere from [[1Bit|1bit]] up to [[8Bits|8bits]], depending on the amount of detail you need. Generally, the lower the [[BitDepth|bit depth]] you use, the more [[Memory|memory]] you save, but the lower the image quality of the transparency.
