If I use the sphere by BB and plug in my HDRI environment maps, will the maps produce sunlight and shadows in Poser pro 11 wirh superfly ? or just global illumination , I mean only the HDRI no additional light .

The basic answer is yes, they will. I don't have any good sunlight HDRIs, but this is a fast, noisy render without any lights, just an HDRI loaded on the EnvSphere.

(For some reason jura's images are not loading for me, so I can't see what he posted).
