Is it possible to add a damage multiplier to somebody's back? It counts as the body/torso or whatever but I'm talking about the back specifically. I wanted to make a knife based on the TF2 knife.

Any help would be appreciated

I am a very enthusiastic modder but I have to say it probably isnt even worth it. You'd have to create whole new meshes and damage bits and peices. I dont really know..... . Carry on.
