not to go off topic.....what a shame Poser dosen't have a python script to allow their (hdrlabs.com) sIBL/fgui setup to work within Poser. Load the IBL light, pop in the corresponding sunlight and specular light with accurate positions and the provided environmental map into BB's environ-sphere.  Ive been doing it for a while but manually, lol. That would be amazing!!!!
