Well spotted - the glass sphere (as well as the glass statue) simply use
"interior { caustics }" to give some impression of the light traveling through
the material.

I haven't got around to trying photons yet in my rig - it may well work by
taking a very low number of samples, since in effect you end up with 400 times
as many if you do 400 passes.

Cheers,
Edouard.

Thank-you very much. I find it interesting to see how realistic a render one can
do with a vanilla version of POV, and mcpov is an amazing benchmark to try and
match.

Cheers,
Edouard.

I've taken Sam Benge's FastSSS macro (from his fastprox include file) and
modified it to suit my render rig, and also changed my bank light macros to put
the current frame's light position into the SSS calculation. It's still all
faked, but I think it's got promise. Seems to be adding about 3 seconds to a 3
minute pass.

Here are two passes - the full render is on it's way.

Cheers,
Edouard.

Looks very realistic! Although not like some green marble - more like some
whatever, lacquered (bet it's not spelt that way) with green paint...

*lacquered* it is indeed  :-)   But this is not lacquer, it is definitely 
ceramics.  Well done Edouard!!
