Another "Arnold like building".
as you can see, there is a problem on the stairs. I increased the count
but the problem is the same !
Why ? I don't know...

PS: I will work one my clouds instead of doing buildings again and again
!!!

Actually the same thing is happening throughout, it's just more pronounced
at the steps.
What error_bound, low_error_threshold, recursion_level were you using? Or
better yet, what radiosity statement?

Radiosity is never boring. :) Send it to me to test my radiosity statement
and see if it renders good over here, please. I'm trying to have mine be as
general/simple as possible, so if it doesn't work with this, something is
wrong.

As far as I know this is a bug, or perhaps rather a flaw, in the
radiosity algorithm; a low error_bound does produce sharper shadows than
the default setting, but the shadows are subject to splotchiness. A low
pretrace_end helps, but even so, values below .01 don't seem to have any
significant effect compared to .01.
Probably, the code needs to be rewritten to handle things like this
better. Maybe if it worked more like photons? Dunno.
Anyway, rendering at a larger size should reduce the artifacts, but it's
a nasty workaround.

Yeah, just looks like a low count to me. You can bump error_bound up to 1
for the higher count renderings. Lower values seem to be largely redundant.
I think someone recently posted something about trace level, too. I didn't
pay attention, though. :)
