I need to know how to (after you have a skin in TGA format) you add house color areas to the TGA skin file. Please direct me to or tell me how to go about this.
You could use alpha channels in the skin explained here.
Or you can have the team colors as seperate segment on the w3d and name them HOUSECOLOR01 - 02 and so forth., then when unwrapping just be sure those are hidden.
