Hey now, that's so much better than seeing only blank light panels. Really
improves it.

What were your radiosity settings? Must be a way to clean up those walls.
Seems to me that recursion_limit shouldn't be too high. I like using 2 most
because of how 3 or more tends to react negatively in shadowed places. And
error_bound should be kept low (I like 0.2). Are you loading a saved
radiosity file with always_sample on to try and refine it?

Looking at POV's rad_def.inc file for an example, it has a small
pretrace_end for indoor high quality. All the choices have half of default
adc_bailout.
