Well...you are right, but the models in-game don't have any specular right now, so it could be a good idea.
I need to ask something about animations. Have you seen the Idle anim in SMG and maybe Rifles too, they look like the guy is reloading. What if maybe they were meant to be a reloading animation which was not included in the game? What do you think, should I use them as reload anims? Bad thing is that I can't make the guy throw the magazine in the SMG anim because not all smg have it in the same place (for example p90).
If not I will do the original reload anims which are nothing but the beggining of the shooting animation.
