I model all my images in Moray, well ok I've done a few in native pov
code but 98% is moray so I'm a little rusty with pov coding. These are
the settings for radiocity in Moray, in some scenes it makes a lot of
difference when I turn it on, in others I hardly notice it, except for
the render time:-). Which of these settings is most key to radiocity in
scenes? Also if anyone could give me a simple but informative
explanation of what each setting does I would really appreciate it. PS:
It may sound like I'm a newbie from this post but I'm not.

Brightness: 3.3
Count: 100
Distance Maximum: 0.0
Error Bound: 0.4
Gray Threshold: 0.5
Low Error Factor: 0.8
Minimum Reuse: 0.015
Nearest Count: 6
Recursion Limit: 1

I'm not positive these are the same terms Pov-Ray uses, I've noticed
some small syntax differences in Moray before.

which version of pov do you render with?  that makes a big difference
with radiosity as the megapov version is cleaner (and faster?).  the
megapov docs have guidelines of what settings to start with and there
have recently been many tests of this feature in the images group with
complementary scene files in the appropriate groups.  check those out
and you should be okay.  as for myself, i sometimes play with the moray
settings, but if there is a 'good' scene i want to render, i'll open my
scene file in pov and add some standard radiosity settings i use by hand
in order to take advantage of some of the megapov keywords.

MegaPov radiosity is a whole other animal.  Certainly is easier to use and get
moderate enough
results just by having a 'radiosity { }' in the global block and turning it on (+qr).
'brightness' in the official version doesn't do anything really, far as I know, except
show a
change in the mosaic preview.
Most important probably would be the 'gray_threshold' and 'recursion_limit', the
threshold being
how much color-bleed to do with near zero being more and nearer 1 least.  Recursion is
how many
times to recalculate the samples I believe, MegaPov breaks the 2 barrier for it. 
Count is the
samples so it's a prime factor in smoothness.
The 'minimum_reuse' is a kind of stepping stone into how the samples are checked,
whether nearer or
farther apart.  Of course I can only try and explain those things in my own way so
that's not
altogether a good thing.
And distance maximum is the difficult part, being scene scale dependant, but once
again using 0 or
MegaPov is a easy way around it.
