Wow, this is incredibly useful information.  Thanks to both of you. Agiel, if you are around and see this thread you should put this in the backroom under Poser-Vue Integration.  

VinceBagna, I see that in your Poser node setup you have applied an Edge blend to the Ambient and Alternate Diffuse nodes.  I think this might be the key. I generally just ignore those nodes, but I think it makes a huge difference in the quality of the Vue render you created.  It looks terrific.  Thanks again for the tips.
