That is real good information, thanks! There is another venue you can tinker with, there ia a plug-in for HDRShop called LightGen, you take a HDRI image and run the plug-in on it and it will create a text file with X,Y,Z coordinates of 20 or so points of light and their colors. (You can use 10 or even 30 or more) You take this information and create point lights at the specific coordinates, color them accordingly, and ta da! You can then use the HDRI image, converted to a JPG, as a reflection and/or environment map. Example file using the "Kitchen.HDR" image and 10 points for lights.

If you give it a try, please post a WIP. I will get some time this weekend and give it a go then. TMG
