Hi all,
In an attempt to get a clean render, I am trying to tune
the radiosity settings for the scene.
With the following settings I get round splotches as shown
on the attached image. I tried various changes in the settings
making the splotches smaller, or changing their location,
but to date, I still have round splotches. (I manage to find these
by comparing with other settings renders ; with nearest_count 10
splotches move and are less visible, yet there are still splotches).
Has anyone of you encountered such splotches and managed to
get rid of them ? Any suggestion ?
Here are the settings :
global_settings {
charset utf8
adc_bailout 0.001
max_trace_level 10
#if(Rad)
radiosity{
pretrace_start 0.04
pretrace_end 0.02
count 300
nearest_count 5
error_bound 0.07
recursion_limit 1
low_error_factor .5
minimum_reuse 0.01
brightness 1
adc_bailout 0.01
}
#end
}

P.S. Splotches are apparently linked to reflection finish
(finish { reflection { 0.0, 0.5 } }) of the dragons. The same
scene with matte dragons has no splotches...
