The main thing accomplished in the Vue render is proper shadows, especially as cast by the hair on the woman's face and the AO bringing out depth in her face.

This appears not to have been achieved in the PoserPro render, even though Poser is perfectly capable of it.  Yep, that would have made the PoserPro render take longer to cook, but I'd make the case that by engaging Mec4D HDRI/.exr lighting, plus AO in nodes, plus agressive settings, you could equal the Vue render.

Same for Carrara. I recently threw 8 hours into playing/learning GI in Carrara, although it was all about reaiistic sky and sunlight on the face in hyper close up, with intense strand hair.

What you need here is a universal scene that we can all take a shot at wlithout violating any copyright issues. Then, distribute that scene and let various people have at it.
