Btw, i'm not beeing an ahole here, but you do realise changing the texture does not make the model unique. For that you need to redraw it in say 3ds max and make your own UV maps. Kinda like the guys are doing with the Battlefield mod. Build the entire 3d model from scratch, then you can call it yours. Untill that time it's simply a modification of an ACM model.
That dosn't mean I'm against it. Not at all! Please put those models to good use lol. Ripping the models and putting them back into engines like Unity or UDK is the closest thing we are ever going to get to an actual SDK for ACM. :-)
