If you want to just have one material for all of the body skin materials, just merge those materials in the obj file of the character. There was a post a month or two about how to do this - looks like there are a number of ways. I personally use the Compose utility. The other way is to use a python script. For example the RealSkinShader/HyperReal scripts give you slider control for spec and apply to all materials. Editing a node name....AFAIK, the only way to do this is to save the material, edit the material file in wordpad and change the name, then reapply the material. (You could also edit the pz3 scene file).
