So, i will make this question short here, how do i make shirts or coats to tf2 in blender? Or more importanly, how do i rig them? Do i need to secelct a specific area and attach it to a bone or something? And how do i do that?

HellJumper, you are credit to tf2 community.

So, i start blender and import a smd spy model. And what happens? The spy model has a mask for some reason, and i cant model anything to his face. I can remove the mask by deleting it, but its time consuming and is not that efective. Is there any way i could remove the mask with a click of a button?
