Thanks! I'll tinker with the radiosity settings. It's so helpful to know what to
work on. I see that my settings must be way off, judging by the table below. The
"Final" number is almost the same as the "Total" number. I appreciate your help
very much.

radiosity {
   count 300
   error_bound .02
   pretrace_start .08
   pretrace_end .004
   recursion_limit 2
   normal on
} //radiosity

  Pass     Depth 0    Depth 1           Total
---------------------------------------------
  2              1        330             331
  3              6       1002            1008
  4             48       7766            7814
  5+           277      27392           27669
  Final      61083    1057679         1118762
---------------------------------------------
  Total      61415    1094169         1155584
  Weight     0.092      0.047
