LOL LOL yeh well I fliped both to exparement each seperately of course to test render. They come out the same either way... try it dont just scold me because I dare to see the effect. Who cares what wasnt said where testing all ideas , dont we all wanna know whats bull and what works ? :) And its obvious after testing flipping either does not change several issues but creates new ones. all it does is reposition light from left to right or right to left NOT front to back. post 48 I clearly showed what IBL map I used. jimmny crickits. Humm somethings amiss Paul. My test rig is very basic No tricks or secret , just infinity cove with caths lattitude map diagram on it and on IBL light with her IBL light diagram pluged in as the light map. My results are not yours as we can see. posts 40, 42 ,43 ,76 , and 77 are just the angular map in post 49 for the IBL, and caths lattitude map on the back drop. Very simple test rig. If the light matches the backdrop colors will not conflict but be correct and sphere will behave as light map dictates. if I flip the back ground or the IBL (doesnt matter same result)you get the effect that seperates 76 from 77 ... Try it dont just say sure.. LOL than you'll see the whole scoop. My point is for me that caths Idea works fine for her ...she built around how poser behaves. but you find flaw and seek to push your script. But I test your idea against hers and find a new flaw thats worse in color effect. That you dont seem to see or address. If you flip back ground light is out of phase. LOL "At what point did reflections come into this? Bring reflections into the equation is just giong to confuse you even more. Get the basics right first, then take it from there." At the title realizm . If I stand against a brick wall and have a white shirt on with my hand out. A ping pong ball in it and you face me and the wall the ball is white still LOL the edges are colored by my hand both by reflection and radiosity. If on the left is blue light the right red bottom green top yellow the edges of the ball pick up the colors. just as post 76 I got what your saying Paul thanks. Maybe slightly smarter and experianced than you think. Maybe Hummm your not seeing the problem because your focus is on your idea and not what my rig shows. I honestly would Love for Cath to finish her tut ... Reminds me of eki's days and lightwave. He and Cath seem on the same flow ... know how the software behaves and trick the camera for top realizm.Poser 6 does rock ! Sorry Cath to disrupt. Night all. Jrabbit
