I've got a scene with radiosity, when I render it with focal blur
it's *much* brighter than without. So what's happening?
The radiosity settings were taken from Nathan's web page:
ini_option "+QR"
ini_option "Preview_Start_Size=16"
ini_option "Preview_End_Size=8"
radiosity{
count 35 // CHANGE range from 20 to 150
nearest_count 5 // CHANGE range from 3 to 10
error_bound 2.25 // CHANGE - range from 1 to 3 - should correspond with
Preview_End_Size
// 1 : preview_end_size = 4
// 3 : preview_end_size = 8
// use preview_start_size = 16
// you can go lower than 1, but then you probably will want
to set
// preview_end_size to 2, which is really slow
recursion_limit 3 // CHANGE
low_error_factor .5 // leave this
gray_threshold 0.0 // leave this
minimum_reuse 0.015 // leave this
brightness 1 // leave this
max_sample 2 // CHANGE - this should be the same as the brightest object
adc_bailout 0.01/2 // CHANGE - use adc_bailout = 0.01 / brightest_ambient_object
}
And the focal blur settings are simply:
aperture 0.05
focal_point <0.0, 0.3, 0.0>
blur_samples 40
