However, look at the strange things that happened.

I changed the name of the Hair TransMap from "...Hair Displacement Map" to "...Hair TransMap" in order to match your terminolgy.  Yet, for both the first name and second name, VSS selected it  for the Bump Map.

Meanwhile, the actual bump map called, "...Body4Bump" was completely ignored. 

Even more strange, it placed the actual displacement map correctly (veins - although you can't see any in the final render) but that image's name is "...BodyBump0"

I know you love a good challenge.  Here it is.  What happened?
