Are there any existing new-mapping textures which use the brow transparencies?  All the textures I've seen have the brows painted on to the skin texture.

Good point! I'm such a knuckle-head sometimes.

So, are there? Would anyone be terribly inconvenienced if I changed the UV mappings for the brow overlay geometries at this point? Please speak up!
