Has anyone else noticed this issue with radiosity in beta 38? I don't want to
report it as a bug because I'm sure I'm doing something wrong since nobody else
has mentioned this, but is there a new radiosity setting that I'm missing? I've
tried lots of things to figure out what I'm doing wrong... The scene renders
fine with radiosity turned off. Here are the radiosity settings in the scene:

      radiosity {
         count 300
         error_bound .02
         nearest_count 16
         adc_bailout .1
         pretrace_start .008
         pretrace_end .0002
         recursion_limit 2
         normal on
      } //radiosity

I know these are somewhat extreme pretrace_start and pretrace_end settings, but
the image is 11400 x 6000 pixels. The scene is lit by a big white dome behind
the camera, and some light_groups.

I just thought I'd mention it.

   Perhaps still using "ambient" on the finish instead the new "emission" 
keyword? :)

Aha! I feel silly! I read about "emission" and made a mental note to try it out,
and then forgot about it. That was the problem. Thanks very much Jaime!!!
