Hello,
<p>i've rendered an old scene with UVPOV 6.2, and it takes much longer
as with 6.0.
<br>The second thing was, .that the scene looked strange (see at the picture
'radiosity_uvpov.jpg' in the attachement).
<p>Rendering times for the scene: 0:47 min. UVPOV 6.0
<br>
4:14 min. UVPOV 6.2
<br>Settings used:
<br> ini_option "+QR"
<br> ini_option "Preview_Start_Size=16"
<br> ini_option "Preview_End_Size=8"
<br> radiosity {
<br>
brightness
2.5
<br>
count
150
<br>
max_sample 1
<br>
distance_maximum 0.0
<br>
error_bound 0.4
<br>
gray_threshold 0.1
<br>
low_error_factor 0.4
<br>
minimum_reuse 0.01
<br>
nearest_count 10
<br>
recursion_limit 1
<br> }
<br>I've also rendered the scene with various values for count (100 up
650), error_bound (0.1 to 1.0) and low_error_factor (0.1 to 1.0).
<br>As light i've used the standard light_source and also the spectrum-light
(only one light in scene).
<p>The second bug:
<br>After restart of the rendering, the right wall becomes holes. I have
tried a heigher value for max_intersections (like 128), but with no effect
(see picture 'radiosity_uvpov2.jpg'). After restarting povray the scene
renders normally (but only the first time...).
<p> Bye
