SSMF: Detail Textures

Detail Textures
Detail textures are made by adding a texture to each channel of an image.
There are a total of 4 texture slots available. One for R, G, B, and one for the Alpha Channel. When you have your detail textures ready, save the file as splattex.tga (Targa - 1024x1024) and place it in the maps folder alongside splatdistribution.tga
