H all around,
I'm not quit sure if this is a bug or a misunderstanding but I tried to save
radiosity data within an ini-file to restart a longer rendering again. First I
rendered the Scene with the ini-options
Antialias=on
Antialias_Threshold=0.3
Antialias_Depth=3
Input_File_Name=Labyrinth.pov
Width=1920
Height=1080
Radiosity_File_Name="Labyrinth.rad"
Radiosity_To_File=on
Render_Pattern=3
Render_Block_Size=8
and later I wanted to resume the Rendering with
; Persistence Of Vision raytracer sample file.
Antialias=on
Antialias_Threshold=0.3
Antialias_Depth=3
Input_File_Name=Labyrinth.pov
Width=1920
Height=1080
Continue_Trace=on
Radiosity_File_Name="Labyrinth.rad"
Radiosity_From_File=on
Render_Pattern=3
Render_Block_Size=8
but POV ignored the Continue_Trace and the load of the radiosity file completely
and started to calculate the radiosity from the beginning (usually with +C at
the command line without loading radiosity data from disk POV calculates the
radiosity only for the not rendered parts of the image). May be this is due to
the use of an other render pattern (I wanted to render the most difficult parts
first).
May be I misunderstand the documentation, has someone a hint?
Best regards,
Michael

2nd paragraph: "The Continue_Trace option may not work if the Start_Row
option has been set to anything but the top of the file ... "

Many thanks, James. Yes, I tried a test today with the standard Render_Pattern.
Continue works now, but the stored radiosity data are still ignored (some 5
hours I would like to spare). May be I forgot a parameter to be set within the
main Pov Scene (and it was not always_sample).
Best regards,
Michael
