I am wondering if it is possible to use a separate shader on a model for a certain area. I would like to assign a different shader to the gum line and around the eyes although it is the same piece of geometry. I guess I could select the faces but the mesh is very dense and I wondered if there was a easier and better way to go about it. For example is there a way to work with the texture map so the shader will only work on that part of the model.

Many thanks,
