Trevor, the above info would make a great addition to your next update,
it really helped me out with getting my setup correct.
The gargoyle is my favorite, the amphora turned out neat (very subtle)
... some of the shading on it comes from edge detect as the spots
orbiting the objects are shadowless, they just fill in where the
overhead center, the mezzanine, and the sun set lights didn't hit. I
also seem to be getting good mileage from have the orbiting object
lights as the cam position for the edge/crevice detect.
Thanks for the addition to my toolbox :-)
Jim
