How can I remove some shadows? is it that I'm using an area light or using
radiosity?
Here's the code:
#include "colors.inc"
#declare Radiosity=on;
global_settings {
assumed_gamma 1.0
//max_trace_level 25
#if (Radiosity)
radiosity {
pretrace_start 0.08 // start pretrace at this size
pretrace_end 0.04 // end pretrace at this size
count 35 // higher -> higher quality (1..1600)
[35]
nearest_count 5 // higher -> higher quality (1..10) [5]
error_bound 1.8 // higher -> smoother, less accurate
[1.8]
recursion_limit 3 // how much interreflections are
calculated (1..5+) [3]
low_error_factor .5 // reduce error_bound during last
pretrace step
gray_threshold 0.0 // increase for weakening colors (0..1)
[0]
minimum_reuse 0.015 // reuse of old radiosity samples
[0.015]
brightness 1 // brightness of radiosity effects
(0..1) [1]
adc_bailout 0.01/2
//normal on // take surface normals into account
[off]
//media on // take media into account [off]
//save_file "file_name" // save radiosity data
//load_file "file_name" // load saved radiosity data
//always_sample off // turn sampling in final trace off [on]
//max_sample 1.0 // maximum brightness of samples
}
#end
}
#default {
texture {
pigment {rgb 1}
#if (Radiosity)
finish {
ambient 0.0
diffuse 0.6
specular 0.3
}
#else
finish {
ambient 0.1
diffuse 0.6
specular 0.3
}
#end
}
}
