The "c:RenumberPOVrayFiles.exe" is actually "c:\RenumberPOVrayFiles.exe" with
the "\" included. The path + program name is correct.

I don't really use the shell commands, so I have no idea.
Maybe use some program that would be super obvious, and just run a test scene.

Yeah - I had a question about that too in some other thread that I can't find
(because Google doesn't fully index our site, in spite of Chris Cason's many
attempts to ensure they do)

I'm guessing you're going to have to find some workaround.

I also have no idea if exposing the full filename path to the user has been
implemented in Willaim Pokorny's yuqk fork...

Any chances it may expect "/" rather than "\"? Just a wild guess, in 
theory, in "" everything must work (are "" really a part of command 
line? I mean, are they passed to the system? Any chances you have to 
double them, like '""'?)

by default "we" are not allowed to run shell commands, to avoid a potential
security issue.  in your global 'povray.conf' file, the "[Shellout Security]"
must be enabled / "allowed"; it is a good idea, generally, to tune the global
..conf and .ini files as part of "post installation".

I've not tried, but can you not write:  post_frame_command = sh myscript
path/to/%s

?

given you have a "target" directory, the 'output_file_name' can (should ?) be a
complete pathname, eg "output_file_name = C:/path/to/selectfolder/myscene". also
use the 'all_file = on' option and POV-Ray's screen output will be (largely)
duplicated in a 'alltext.out' "log" file.  and re your Delphi code, what if it
takes two arguments, that is path and %s separately ?

The program can take any number of arguments*, or at least maybe a dozen of
them. (I never could find a limit to them.) But arguments are of little use if
the program doesn't run in the first place.


*) For instance, argument 0 is the program name itself, including its path)

have you checked your global ("system-wide") 'povray.conf' wrt permissions ?
(your private/user 'povray.conf' too, of course :-))

if your permissions are ok but your program doesn't run, it may be an
environment / $PATH issue; your code may only see a subset of the environment
(variables) POV-Ray sees.

Yes, I think jr was trying to reference
https://wiki.povray.org/content/Documentation:Unix_Section_4

With regard to giving povray the necessary permissions for invoking executables.
(Sorry if you've already tried that - it wasn't clear from the thread if you had
or not)

FYI, I found that execution of external programs is disabled by default. You can
enable it in "Options" -> "Script I/O restrictions" and uncheck "Disable
starting other programs". Now

    Post_Scene_Command = c:RenumberPOVrayFiles.exe %s

indeed runs my program, but the parameter %s is still not recognized.

check your program ?

fwiw, I'd write a simple shell script, and supply and check the expansion of the
seven substitutions available.
