I am making a game, and you build cars with guns, however i am having an issue at the moment, and i do not know a solution to the problem. The issue is, that i want to be able to place things, like a tire on a block, but i dont want to be able to place things on certain faces of the tire, for example the tread on the tire. I was wondering is there was a way to tag faces, or have somthing that will work in the same way.
