Looking around in the PyMel docs not finding too much info on FBXExports
via PyMel. Anyone got any info?

Thanks in advance,
Eric T.

Been doing a ton of stuff with FBXExport lately. I recommend just going
through mel.eval(). I've experienced a lot of weird stuff when trying to
do it through pymel.

What kind of weirdness? do you have any stack traces or examples? I'd like to see if it's an unknown bug or if there are problems like having an argument called "import" or something that will break python.
behind the scenes pm.mel is doing mel.eval so there shouldn't any weirdness.

Most of it was back when I was dealing with passing arguments to FBXExport; a lot of what I remember getting was TypeErrors and I was sick of dealing with it (since I had a Qt Gui and was already doing a couple of type conversions here and there), so what I ended up doing was just writing my own method to take in simple bool args and return the correct FBXExport strings to be evaluated.

Also some FBXExport methods that don't work between versions of Maya, if I use mel.eval, it's easier for me to catch them too. (e.g. FBXExportReferencedAssetsContent is 2014-specific)

I don't really have any isolated code samples on hand unfortunately...

Just as a follow up, how does one suppress the warning messages that
may appear? I'm trying to run a script that batch converts a list of
Maya files to fbx and any time a warning pops up it freezes the
process. Most warnings I don't care about...

This should help.


Store state on batch execute, disable, then re-apply stored state on batch complete.

there is no pymel api for FBX to my knowledge, BUT
you can python-ify your calls by using pm.mel
then the mel command is python. try it.

import pymel.core as pm
pm.loadPlugin("fbxmaya") # LOAD PLUGIN

# EXAMPLE SYNTAX
# pm.mel.FBXCommand(args)

#for example
pm.mel.FBXExport(f="FILENAME")
pm.mel.FBXImport(f="FILENAME",t="TAKE")

The issue here ultimately boils down to the FBX* commands not using the standard Maya ArgParser syntax and just reading the Args directly out of the command. So that's not super epic.

An option for this if you don't want to use PyMEL in your pipeline is to either call the MEL commands with maya.mel.eval()... or otherwise check out this excellent Blog post suggesting a nicely Python-wrapped workaround for these kinds of offending plugins:

Thank you so much. I have been going literally insane trying to get this to work
