I've identified what I believe is a bug when using POV-Ray for rendering images in LPub3D. When the directory path to the LDraw file does not contain any spaces, POV-Ray is invoked successfully and the appropriate images rendered. An example of the command line generated by LPub3D to invoke POV-Ray (from the POV-Ray log) is:

Code:

Preset INI file is 'D:\USERS\VISTA\DJM\DOCUMENTS\POV-RAY\V3.7\INI\QUICKRES.INI', section is '[800x600, AA 0.3]'.
Rendering using command line '+ID:\users\djm\personal\2017\LEGO\BUILDI~1\DACHSH~1\LPub3D\tmp\PLILDR~1.POV
+OD:\users\djm\personal\2017\LEGO\building_instructions\dachshund\LPub3D\parts\4589_128_1753_150_DPCM_1_23_-45.png +W1753 +H1240 +UA +LD:\PROGRA~1\LDraw\LGEO\lg
+LD:\PROGRA~1\LDraw\LGEO\ar +A'.
Rendering with 2 threads.

However, when the directory path contains a space, POV-Ray generates an error (from the POV-Ray log);

Code:

Preset INI file is 'D:\USERS\VISTA\DJM\DOCUMENTS\POV-RAY\V3.7\INI\QUICKRES.INI', section is '[800x600, AA 0.3]'.

This is not a valid command-line. Check the command-line for syntax errors, correct them, and try again.
Valid command-line switches are explained in detail in the reference part of the documentation.
Failed to start render: Failed to parse command-line option

Note the difference between the respective +O command line argument quoting. The first (without spaces)

Code:

+OD:\users\djm\personal\2017\LEGO\building_instructions\dachshund\LPub3D\parts\4589_128_1753_150_DPCM_1_23_-45.png

compared to the second )with spaces);

Code:

"+OD:\users\djm\personal\2017\LEGO\building
instructions\dachshund\LPub3D\assem\main_10_whole_rotated_060-00-head_1_0_0_0_1_0_0_0_1_1_1753_150_DPCM_1.png"

I believe the issues may be the double quotes around the entire +O parameter values, causing POV-Ray not to see the +O as intended.

Regards,

David
