[Maya-Python] Importing FBX system changes suddenly

[Lidia Martinez]

All my process was ok. I used cmds.file( path, type = "FBX", return new
nodes.... )

Now i execute and tells me "FBX" is not a known type. ?¿¿.
I import by hand and says its "Fbx". It was working days ago. And a window
for the settings appears now, making all my script fail.

I wonder what the hell happened from Thuesday. Is it an unexpected update?.
did somebody entered my pc at work? (ankward). It was working, i imported
fbx files, no prompt, FBX with uppercase worked...

I read here:
http://knowledge.autodesk.com/support/maya/learn-explore/caas/CloudHelp/cloudhelp/2015/ENU/Maya/files/GUID-699CDF74-3D64-44B0-967E-7427DF800290-htm.html
...
It is not recommended to use python file's command, but fbxImport from MEL.
O_O not a "return new nodes" parameter available now... so i have to
rewrite everything i did.

Does anybody know what happened here?.

What version and OS first of all?

I've had similar problems where my scripted FBX process suddenly changes.

After choking through a lot of help docs and tutorials, I've been
(relatively happily) using PyMEL's mel module, as suggested in this TAO
thread:
http://tech-artists.org/forum/showthread.php?4988-Problem-doing-an-FBX-export-with-PyMEL

Example from the thread:
pm.mel.FBXResetExport()
pm.mel.FBXExportBakeComplexAnimation(v=False)
pm.mel.FBXExportConstraints(v=False)
pm.mel.FBXExportInputConnections(v=False)
pm.mel.FBXExportUseSceneName(v=True)
pm.mel.FBXExportInAscii(v=True)
pm.mel.FBXExportSkins(v=True)
pm.mel.FBXExportShapes(v=True)
pm.mel.FBXExportCameras(v=False)
pm.mel.FBXExportLights(v=False)
pm.mel.FBXExportFileVersion(v='FBX201300')
filename = 'path_to_export_file'
pm.mel.FBXExport(s=True, f=filename)

That is probably not your issue and it would be nice to know what happened,
but maybe it will work.

Hey Chris!,
Thanks for the link. That gave me an idea.

I'm on Windows 8, Maya 2015, FBXplugin 2015. FBX file imported came from
3dsMax , fbx plugin version 2010. And then tried 2014, and gave me the same
errors.

Found this thanks to your link
http://techartsurvival.blogspot.com.es/2014/10/laziness-and-cleanliness-and-mel-oh-my.html

I wanted to avoid using PyMEL. But i think i'll finally end up using it
anyway. :-D

I read there is a cmds.FBXImport method created in maya.cmds. I'm trying
that out...


but anyway, i thought it could be some kind of conflict of names with "fbx"
string. I unloaded FBX plugin, and no FBX format is allowed. That's ok.
Then activated it once again, and saw on its info that it adds "File
Conversions: Fbx, DAE_FBX, and others...". So FBX is no longer present, but
Fbx (???)! Great, hopefully i can use it on cmds.file() like before...
I wonder where FBX came from when i was working last week..

Trying to use Fbx in the cmds.file( ) And works, but the code continues
executing, no matter what happens with the importer. A screen asking for
settings appears, and my script fails (import is not finished,but code
continues executing...O_O. Not modal prompt)

Then i try to use mel.eval( "FBXImport -f " + path) <-- which is said to
be an import process with no import options screen opening. But then i get
this great window telling me there is an error, and the file is either
corrupted or either an incorrect version. WTF!, if i import the file using
maya menus, it works and imports ok. The version, maybe it's 2014 or 2010...
But FBXImport doesn't have any option to tell it to ignore version.


This is so funny....

Using cmds.FBXImport hopefullly helps... But there is no option for
ignoring version.

An interesting update on this issue:

My neighbour coworker has Maya 2015 SP5 extension 1. In the plug-in
manager, in the fbx plugin info, says it adds: FBX, FBXExporter, FBX_DAE,
and another one (4). I have Fbx (!!), FBX_DAE, and the other one. but not
FBXExporter and uppercase FBX.

We checked the version, it's 2015.1 . both... but we have different
information.

I installed the SP5 and extension 1. Nothing changed, i still have Fbx and
the other two. Nothing changed.


It's about the fbx version. But this doesn't fix it. Does anybody know a
workaround?
