Ha, I am sitting here in front of my pea sea, playing with this model 
right now.  What a welcome diversion.  I was in the midst of doing 
just that, as I am re-creating my radiance scene description after a 
very abrupt lesson in the whims of gzip (don't ask).  

I am building a separate model of one coffer, for the mkillum 
process.  It would be trivial to place it in a small box room for 
further study.  I would be happy to give you the files when they are 
ready, which is likely to be sometime tomorrow because a show 
about the Reno Air Races is airing on TV soon.  =8-)

As for the bug's relation to my current woes, well, I don't know.  
The renderings that exhibited this problem are old.  The latest 
renderings (the ones at the end of my web page on all this) do not 
have any of these artifacts.  The problems I'm currently having with 
the rendering of the coffers is more of an uneven illumination inside 
the coffers; there are no strange artifacts. But if my model can help 
you guys analyze this elusive bug, I'd be happy to send it to you.  
Let me know.
