A diffuse map contains the color information of a 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. | ||

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. | |||
