Well, let me explain why I used them, and hopefully someone can tell me
where I went wrong.
radiosity {
#if (pass1)
pretrace_start .04 <--- The pretraces, I reduced in size to get
a little more variation in the colors and shadows of that big, blank far
wall, by avoinding large sample areas.
pretrace_end .01 <--- See above
error_bound .1 <-- I reduced the error bound until it looked good.
Larger is too low quality, and lower changes very little.
minimum_reuse .0025 <-- The default.
nearest_count 20 <--I was using this because that's what Tim Nikias
reccomended for 2 pass radiosity. Ensures more even samples, as I
understand it.
count 1200 <-- I used a high count because it looked better. Low
count gives the bland results I posted in p.b.i.
recursion_limit 5 <--- I have several panes of glass in the scene.
Without a higher recursion limit, the scene gets very dark.
brightness 1 <-- The Default
max_sample 2 <-- Increaced for the lights upstairs, which have a
high ambient.
low_error_factor 1 <-- Tim Nikias' value, again.
adc_bailout 0.01/20 <-- default, I believe.
save_file "radios" <--'Nuff said
#else
pretrace_start 1 <-- Pretraces set to one for second pass
pretrace_end 1
count 1200 <-- count set the same as above.
recursion_limit 5 <--same as above
low_error_factor .5 <-- Looking at this again, I realize I never
deleted this. Correct number is below.
gray_threshold 0.0 <-- Default
brightness 1.25 <--Looked better this way. The room is a little dark
w/o
error_bound .8 <-- Value multiplied to smooth out samples
minimum_reuse .0025 <-- Default
nearest_count 20 <-- Tim, again
low_error_factor 1 <-- Same as above
adc_bailout 0.01/20 <--Default
load_file "radios" <--'Nuff said
always_sample off <-- Two pass radiosity
max_sample 1 <--So I can see the partitions in the lights, now that
the light from them is calculated
#end
}
Thanks for your help!
