ya that makes sense, I have to read stuff 2-3 times before it sinks in.

Between king and queen shadows could not fixed at adaptive 0, gave up and bumped
to 1. Still quick by my standard.

New white wood brightens scene
Area light diameter from 15 to 12
Probably a bad choice = lost captured piece light,
complicated by table finish changes.

fixed phong haze/burnout that was in previous image.

I can show a statement in the help file somewhat inaccurate:
(Or that I have no memory)
"Area light only affects shadows" (from memory)

area_light diameter greater than light distance is like setting phong intensity
lower as it's diameter goes up..
less than light distance seems to have little change.
