Make some parts of character model not use textures

Ok so i got a character but for example i only want to see textures on the arm for now. And the rest of the character to be vertex colors how do i remove the body uvs from my arm texture ?

I believe the only thing you can do is select every face that you don’t want to have textured and assign it a new default material. The only other thing I can think of is to break the object down in to parts, like the arms, being separate from the body, than you remove all materials from the body.

That is all I can think of doing.

Thanks How can I assign the other parts a new material on the same mesh? Thats one thing i cant find through google

go into edit mode, select the faces you want to assign to the new material, select the new material and click “assign”:
