Hi all!

I'm a relatively new user to Pov-Ray. I use it in conjunction with other
programs to generate scientific figures, so I have some mild experience, but
I've encountered an error that I'm not sure how to tackle.

The problem is as follows: I generate a Pov-Ray file successfully from one of
the programs I use, and I can open it in the editor without any issue. All the
commands are already present in the file so I should just be able to hit Run and
let it go.

However, while trying to parse the file, the program halts and I get the
following error: "Parse Error: Mesh face index out of range". This is
accompanied by a command line becoming highlighted in yellow, the "face_indices"
section of a mesh2 section.

I'm looking into the Mesh2 section of documentation, but I was wondering if
anyone out there could help me resolve this issue. Any help at all would be
extremely appreciated!

Hi Paul - and Welcome!   :)

Usually when something's out of range (like in an array), you're trying to
access an element that hasn't been defined yet.
If there's a part of the mesh definition that lists how many faces, vertices,
etc - try incrementing that until the error goes away.

Then I'd investigate why the software gets it wrong.

Also, if you [ALT]-[M] to pull up the message window, and select Copy Pane, then
you can paste that here so we can see what the error is verbatim.

This is an indication that whatever software created the file did a bad
job at it.

About 'copy pane', from docs...
"Note: This command only appears if the currently selected window is the
Messages window." Then it shows up under the EDIT menu.

BTW, there are times when the message window is *completely* blank during an
entire POV-Ray session; it's happening right now on my Windows version of 3.7.1
beta 9. No idea why. It comes and goes.

All_Console=on
Verbose=on

(I'm not so sure those are working correctly either, when turned OFF-- I
generally still see some messages, when I'm expecting(?) not to.)

Yes, I hope this is not blender, is it?
If so, feel free to send me the blend file for debugging.
