The newer one 

Clearly, there's a lot more going on with the newer MAT.  When I disconnect all but the Image_Maps, then crank up the Diffuse_Value to 1.2, in P7 I get most of the effect I'm looking for.  I recognize experts may cringe at this ham-fisted approach, but this may be one of those "eye of the beholder" situations, not to mention dropping the process back to a level I understand.  

I do appreciate the assistance you all have given me.  Perhaps when I have time to learn  the subtlties of lighting in Poser, I'll be able to make use of it.

Thanks again,

Dave
