Hi people,
i have a problem with the radiosity setting and glass objetcs.
If i try to set this:
(ambient_light 0)

count 300 (or >)
nearest_count 4 (or >)
error_bound 0.08 (or < )
recursion_limit 1
brightness 2 (or >)

to simulate a global illumination,
any glass object projects some blak dots around the scenes.

Thanks,

Ceggi

Use - global_settings { max_trace_level 10 }

You may need to use a higher value to get the results you want.

Wow,  max trace at 50! That must have been VERY slow!
How long did it take to render?

The max_trace_level attribute only controls the maximum number of
levels traced...it will only do that many levels when they are
needed. This feature works together with the Automatic Depth Control
(adc_bailout), not alone, so it will only make some pixels take more
time...the same pixels that were causing a problem before.
