uh so shouldn't the figure be full on spot light'd (sun over cameras sholder) and fading off to darkness if the camera is fliped to 180 degree then ???? I did this once in lightwave with HDRShop and I used a image that was numbered. by rotaing the camera around in the scene the image mapped to the "ball" I could tell where I was in the scene, (also helped to have a photoshop layer I could turn off later for final render when I found the sweet spot lighting effect I was looking for). I see the sample picture of angular map, but I don't see how it applies to the mini tutorial. I think I'm losing braincells more and more with IBL AO HDRI whooit thingy ....
