This week-end, I tried MegaPOV radiosity and reflection blur.
I made a scene with no light source and only one object with ambient
(the white 'sky sphere' has ambient 1, anything else has ambient 0).
Some questions:
- what are the finish features that only interacts with 'true' light ? I
tried metallic but I didn't see any difference.
- when using low quality rendering, the brightness is false (lower than
the high quality one) must I change brightness to correct it ? what
radiosity parameter is involved ? I'm using:
  count 50
  nearest_count 4
  recursion_limit 1
  error_bound 1.0
for low quality and
  count 100
  nearest_count 5
  recursion_limit 2
  error_bound 0.4
for high quality.
- why is reflection blur corrupting my radiosity ? Must I put more
samples ? (5 in the picture)
I think that's all for the moment. I will try to add a light to get more
effects...
