Maya tutorial on modifying the look of rigged/skinned characters without the need for wrap deformers or nCloth. This will result in rigs that are just as lightweight (or really close!) to the original rig.
The character used in this tutorial is just one example and the freshSkin script and ideas should work on nearly any rig.
You may find that the script will allow you to modify other characters face geometry too, but due to the way the face controls were setup for this character, I could not modify the number of vertices on the face.
The "sculpts" face that I re-sculpted to change the look of the face was the root blendshape for this head. This technique may not work on some rigs, but creating new blendShapes are a valid way to alter a rigs look without adding or taking away geometry. I'm still new to some of this, so there's a lot of guesstimating going on here
