Well patorak,  I don't see anything in that Lightwave GI simulation that Poser can't do, so it should be possible.  It requires parenting a number of lights to specific locations on a "dome" type object. then spinning the object very quickly while rendering with motion blur.  Setting up the rig may take some time as well as adjusting light intensity and such (Python scripting would help here).

If Poser 8 is released with GI, then that may be the prefered solution.  However, if all you have is Poser 6 or 7, then using Bagginsbill's gamma correction technique, plus fake GI, might look awsome.

Also, fake GI means that render times will be reduced to a tiny fraction of what full GI would take.

thanks for the link

take care
