Hi all!
I'm having some problems with getting radiosity to look good in my current
IRTC project.
I've attatched three pictures
bathroom07_small_original.jpg is how it came out from POV-Ray
bahtroom07_gamma.jpg is gamma correceted to se the detais
bahtroom07_target.jpg is an gamma / brightness / contrast altered image, and
is somewhat what I aim for.

I tried using two lights, and it looked better, but you couldn't even spot
the light beam from the door, and that is an important part of the scene.
I'll model seperate tiles for the walls and sink, any tips for a good, clean
ceramic texture?

I use the following rad settings: (uses Jaimes save/load trick)

global_settings{
 assumed_gamma 1.0
 ambient_light 0.0
 #if (R)

iosity{ 
// indoor quick settings from rad_def.inc
    #if(R_Save)
          pretrace_start 0.08
          pretrace_end   0.01
          count 50+100
          nearest_count 5+15
          error_bound 0.5-0.25
          recursion_limit 2
          low_error_factor 0.8
          gray_threshold 0
          minimum_reuse 0.015
          brightness 1.0+1.5
          adc_bailout 0.01/2
          save_file "bathroom.main.radiosity"
    #else
        // load settings  
        pretrace_start 1 pretrace_end 1 
        load_file "bathroom.main.radiosity" 
        error_bound 0.5    // it's important to specify the same value used to save
data
        recursion_limit 2  // also the same if specified
        always_sample off  // no more samples: specially useful with focal blur
    #end
 }
 #end
}

The rad is collected in 320x240 res with dummy objects and no finishes (~45min). And
then rendered in 1280x1024 (~1hour)

Any help appreciated!

Kind regards
Peter
