Thanks for the encouragement Kenneth! I will keep plugging away. One issue
regarding the pigment gradient is that not all the pyramids have the same y
value for the bottom of their pit. So I struggled finding the *best* value since
it worked for some but not all. Do you see any way around that?

Alain, I will also give the orthographic camera a shot, thanks for that
suggestion.
