First a little background. The attached link is of the best model of Global Illumination I've seen to date. Secondly lets recap how Poser 5's Light Setup is, and see if we ca'nt visualize, at least for a moment, how the Bryce model could be replicated in Poser 5. The 1 light is positioned at 0,0,0, in the left image. The Y and X coordinates mark where the light will move if you slide that light's coresponding Transform(Movement) Dial posotively or negatively. Once the the Y position has been moved from 0 the Z Transform dial becomes functional. The Z Transform Dial will force the light to circle around the Y=0 point, 360 degrees. As shown by the contrast between image 2 and 3 the more the Y Transform is offset from 0, the Larger(And we'll get to this in an argument...) distance the Z's Transorm Dial's 360 degrees will actually cover. = )
