Miss Nancy:

The water in that sceen is just flogging the CPU with calculations when I try to use IDL on it. I did what you said in the above message, and got an idea. I set one light source to no shadows, and put it at 15%, and set a Raytraced light to 85%. These lights do not respond to XYZ coordiates but they do respond to XYZ rotation coordiates. With the same rotations, the lights occupy the same space, and I have in effect one sun that can fill shadows with light. I am experimenting with blurring the raytraced stronger light to get a pleasing balance. This is not as good as IDL, but it is better than the results I was getting before. Thanks. :)

I wonder if I parent one light to the other if they will both move together?
