Ahh, I didn't know that - I hadn't seen that kind of artefact before.

My settings were:

        radiosity {
   pretrace_start 0.08
   pretrace_end 0.005
   count 20 * radiosity_quality
   nearest_count 5
   error_bound 1
   recursion_limit 2
   low_error_factor 0.5
   gray_threshold 0.0
   minimum_reuse 0.015
   brightness 1
   adc_bailout 0.01/2
         }

where radiosity_quality was 2.

always_sample off seemed to fix it, but I have to admit that I still find the
exact behaviour of many of the radiosity parameters a bit of a mystery.

Ahh, OK - what am I looking for in the stats?

Cheers,
Edouard.
