I've noticed this.  This looks like it is coming from the very dim 'fill'
lighting I am using along part of the projector beam.  The light intensity is
right near the bottom of the colour depth so it tends to get stepped.  I tried
it with HDR image type output and the banding disappears (converting the HDR
back to JPG or PNG reintroduces it).  I may either have to adjust how I approach
this light, adjust the texturing to better mask it, or just get rid of it
completely.

There is a very good reason for this:  durrently those particular parts have a
'rgb 0' pigment attached.

Helps a little.  I think the big problem before was my monitor gamma was bumped
way too high.  However the brightness setting is something I could not find a
lot of information on previously.  When calibrating before and fixing the gamma,
I had bumped this right down (0%), but using your posting I have it somewhat
higher (40%).
