Maya 2019 userSetup.py

[chalk]

Not one for doubling up, wanted to point to an early thread that might offer solutions: http://discourse.techart.online/t/python-maya-startup-script/2145/21 via @bob.w:

However, I would do this a bit differently, instead of passing a string into executeDeferred you can hand it the function object and it will call it for you at the proper time. The nice thing about this is you can pass *args, **kwargs along with it.

import maya

def yourMethodName(standalone=False):
    #do python stuff here once GUI’s loaded.
    pass

maya.utils.executeDeferred(yourMethodName, standalone=True)

My gut is that PYTHONPATH is being set on Maya start up, but some higher priority tool, plugin, is overriding it prior to calling the userSetup.py. Can you attach a debugger to Maya and see what its calling on startup?
