I guess what prompted that train of thought is: Kerkythea's strong suit (if I understand the software and the philosophy behind it correctly) is a highly sophisticated approach to lights and materials. Even the way the render is accomplished is dramatically different from other programs of that ilk.

I am quite impressed with the software... and the renders have been quite decent, even with my extremely limited knowledge of how to apply what I learned from a very careful read of the manual.

Which prompts me to say: thank you, Bill, for hand-holding me through the blender node section of the face template... it was a great starting point to better understand nodes in general. Ya gotta start somewhere. Whilst I'll be the first to admit I basically don't touch the other nodes, since I only have a very rudimentary understanding of some of them, and no clue about a lot of them, I want to understand what they do and how. The formulas on bias and gain I've been trying to plug in just to see what I get, but the nodes were the eyeliner ones and it was really hard to assess the differences... need to try on a larger mask, maybe.
