Some people use Vue to generate the background and environmental lighting and then import these into their preferred rendered for the foreground images.  This takes three renders (360 degree hdr in Vue for lighting, detailed background render in Vue for field of view only and final render in other package including foreground objects).

Don't know the quality of the Poser render using this method so I'm just putting this forward as a possible line of enquiry rather than a solution. The link is a very simple Vue+Maxwell render to illustrate the concept.
