-A diffuse map contains the color information of an surface. Often also referred to as albedo, especially in the context of PBR workflow.
+A diffuse map contains the color information of a surface. Often also referred to as albedo, especially in the context of PBR workflow.
+Aside from the color information stored in the RGB channels, a greyscale alpha channel can be used to control transparency/opacity, where black is fully transparent and white is fully opaque.  Note that using transparency in game is more complex than simply adding it to the diffuse.
+Diffuse maps are located in the Data/Textures directory tree and are suffixed with "_d" (e.g., Data/Textures/Clothes/VaultSuit/VaultSuit81_d.DDS).  When the diffuse doesn't need alpha or only needs 1-bit alpha, they are stored in the BC1/DXT1 compression format.  If more than 1 bit of alpha is needed, the diffuse is stored in the BC3/DXT5 format.  Note that block compression is lossy, so the image stored can vary from the original image.
