Making a custom Playermodel.

Hello, I am trying to make a custom player model for a machinima I’m making and I’m wondering how I would go about replacing one model’s head with another head. I’ve looked up and down the interwebz and I can’t seem to find anything on this. Thanks for all of the help.

Shouldent this go in modelling? But as for this you would probbably just remove the head and put the other head in the same place, Then linking up all the vertexes and rigging the head propperly

M’kay… Could you elaborate on that please? I’ve never modeled bofore.

What I’m trying to do is put a human head on the body of a custom model made by shotgunguy. The model is the urban trenchcoat. Please I would like to get this done as soon as possible. Thanks.
