I have been doing animations with Poser and VUE.  For me the render times are horrible when rendering frame by frame in VUE with an animated Poser scene. So I would typically duplicate the lighting from Poser to Vue as much as possible.  Render the background scene in VUE, then composite over the Poser animation and shadows.  If you plan your scene you can get a pretty good result.  Plus if camera is stationary  - compositing can save you lots of time.

Yes, it means two renders but I think I am still spending slighlty less time on it this way.
