The first one is testing one of Jaime's new HDR light probe, the other
the environment from the MegaPOV sample scenes. The table is using
blurred reflection (with the average texture trick) which works very
well but is quite slow (1 hour at this size).
The scene contains different objects for radiosity (without reflection,
refraction using no_reflection and no_image flags) and normal appearence
(no_radiosity flag) so i don't need a two pass render. Furthermore i
tested some new improvements of the radiosity function.

Lovely blurred reflections... with a bit of banding on the brighter
parts, but nice anyhow. It's a pain it can be made faster...

Very interesting tips... really worth trying this weekend, I think.
:) The rad seems very good, and you don't seem to get the artifacts on
the reflections that I get when using two passes (being the first
without reflective textures).

Yes, the banding is normal with this technique. But better than
graininess IMO.

There are some subtle artefacts near the bottom of the spheres. BTW
with recursion_limit 1 instead of 2 and no blur it renders in just above
1 minute.
