Hi Jason, Thanks for replying. Unfortunately, two sided lighting does not help. The example was just to show what I meant by CGO lines (I'm not sure how familiar everyone is with them).
Here are links for 1) the *.py file that creates the objects shown in the images I previously provided and 2) the *.py file that places the new light objects (that still don't fix the problem). 1) http://dl.dropbox.com/u/1209050/3CMX_8_pock.py 2) http://dl.dropbox.com/u/1209050/lightDots.py Cheers, Stephen --------------------------------- Stephen J.
