Hmm, food for thought.

Unfortunately I was sitting here thinking about render tests I had been
doing and kind of spoke out loud here as I wondered about it.  I mistakenly
said how ambient wasn't used anymore when what I was thinking about was the
MegaPOV (okay, okay, I know the phrase) way in which ambient 0 was the norm
for when radiosity was to be done.  Obviously now in 3.5 it's okay to use
ambient light from what I've gathered about it.  Still, what puzzled me is
how diffuse can be so steadfast and unchanging when in an environment that
ought to be affecting it.  I think this is my misunderstanding, since
diffuse is often used as a color buffer, as opposed to a color enhancer as
with ambient.  However, BTW, I tried high ambience too and really only color
(pigment) was the dominant force.

Not sure I'm describing anything correctly here but maybe its still
readable.
