Maya 2018: XGen Expression Editor does not open

[Anonymous]

Hey Maya Pros!

I am recently having issues with the XGen Expression Editor in Maya 2018.1.

When I click the Expression Icon beneath the slider for the parameter I want to edit, no Expression Editor Window opens.

I already tried to reset my user preferences for Maya, but the problem still occured.

When I open the Maya Script Editor I get the message:

# Traceback (most recent call last):
# File "C:\Program Files\Autodesk\Maya2018\plug-ins\xgen\scripts\xgenm\ui\widgets\xgExpressionUI.py", line 1981, in showEditor
# self.xgExprEditor = XgExprEditor(self.attr, self.value(), cpal, cdesc, _mayaMainWindow)
# TypeError: # 'XgExprEditor.XgExprEditor' called with wrong argument types:
# XgExprEditor.XgExprEditor(str, str, str, str, PySide2.QtWidgets.QWidget)
# Supported signatures:
XgExprEditor.XgExprEditor(unicode, unicode, unicode, unicode, PySide2.QtWidgets.QWidget = None)

Hope somebody can help me out 🙂

Hi!

Try a reset of your preferences.
Rename the folder prefs in folder 2018 to something like prefs_backup, or to reset everything, the folder 2018 to 2018_backup. Maya creates new folders. Detailed at:

Hi!

Unfortunately I already tried that, but it did not work....

I started Maya 2018.1 with the default Maya Prefs, everything (including window Layout) was set back, but I still could not open

the XGen Expression Editor 😞

Maybe there is another way to open the Editor via a custom script?..

Hi!

You are right, it does not work.

Please report this problem (bug?) to Autodesk.

Hi @Anonymous,

thanks a lot for pointing out the issue. I could reproduce it on my system.

The issue is already logged with our development team and they are already working on the issue.

Best, Nadja

What's the ETA on a fix for this? It breaks some pretty crucial functionality.

Hi,

i had (and have) the same problem.

Load any expression from the dropdown menu, after that you get a expression inputfield.

Hi, this bug breaks basic functionality of Xgen. Any ETA on a fix? Thanks.

Did anyone find a workaround this one?

[Anonymous]

This is absolutely ridiculous!!! I was working on a character for a month and suddenly xgen breaks? wth?????

 TypeError: # 'XgExprEditor.XgExprEditor' called with wrong argument types: blah blah

the simplest thing that you can do these days is to paint on something in 3d packages. why do I need to spend 10 hours trying to ENABLE? painting maps? seriously?

Has this been solved yet?

Hi!

It's fixed in Maya 2018 Update 2.

[Anonymous]

Wonderful! Has anyone here tried this out?

[Anonymous]

No. Using 2010 if I ever need to open a Maya scene.

Hi, I have this same problem with xgen, in my maya 2018 and now 2019. I just reinstalled both and still doesn't work :

I don't see any unicode character in my path... any idea to solve this problem?

Thanks

This worked for me. I duplicated my prefs folder [just incase], and deleted the files in the original prefs folder. Once I relaunched Maya 2018, the XGen editor launched.
