Lighting is my nemesis too.  I've been experimenting with everything at once-IDL and IBL plus a spotlight for using Inverse Square Law lighting.  I set up two figures, one a little behind the other with the spot light (with Inverse Square Law-ISL- activated) in front of the first one, the IBL light centered on both.  Haven't tried Specular Lighting yet.  I sort of like the results. Jan
