My attempt at nice radiosity. The model is from Sci-Fi 3D. Render took
7.5 hr on an Athlon 800.

hmm, looks a touch better than mine, better lighting depth. what's your
scene?

Here are the relevant parts of my scene. No light sources were used. The
colour(s) may be slightly different in the pic I posted, but the rad
settings are the same.

With those settings, consider making adc_bailout and low_error_factor 1,
and experiment with lowering nearest_count and increasing the pretrace sizes.

Thank you. I'll try those suggestions and see what comes out.

That's looking very smooth, quite a bit too smooth IMO. A lower
error_bound could improve realism IMO.
7.5 hours is also ridiculously fast for such a scene... ;-)

*Very* nice radiosity!
