I've been thinking of a way to do radiosity only specified objects. What I've
come up with is basically adding photons to Ron Parker's blurred reflection so
that you get blurred caustics. Unfortunately, as you can guess that gets to be
_very_ slow. So slow I can't even get a render finished overnight with a simple
test scene. I'm not sure how to optimise photons for speed, so maybe someone can
help me there?

I've posted what I've got on PovRay.text.scene-files.

Comments?

I have been thinking of a switch to turn radiosity off for
selected objects.

If this works that shouldn't be a problem. I just don't know how to make it fast
enough to be usable. What good fast settings can I use with photons/caustics?

I would prefer object{... no_radiosity} but it's a feature
request. Someone suggested this before.

I would prefer it if you could define several 'extra' radioasty blocks, then
assign different objects different rad settings
