I finished the normal map and phong map, it turns out very nice ingame (the phong is similar to the one of my DoDS Sten release). As Cigano found a smoothing error, I recompiled the weapon with an updated model from RedRogue, seems like they're fixed. I also mixed a shooting sound together from various sources. It sounds now pretty similar to the sounds I heard in some youtube videos.
This compile and texture set is finished, now we all have to wait for Cigano to finish his texture.
