Unable to open scenes with walter nodes using mayapy

[espennordahl]

Whenever I try to open a maya scene that contains a walter node with mayapy, it crashes. This is reproducable by creating a walter node in an empty maya scene, saving, and then from another terminal running mayapy: import pymel.core as pm; pm.openFile(myfile, f=True, prompt=False)

I'll try to work around it using mel, but nothing else in or pipeline is mel, so it's a bit of a pain.

Thanks

Hi! At Rodeo we have scenes opening with mayapy all the time and full of Walter standins all over. There must be something else odd going on if it's crashing for you.

Do you have a traceback you could paste us here so we can see what the crash looks like?

Would also be helpful to know the Maya, Arnold, MtoA and OS versions you're crashing with.

Thanks.

Thanks for getting back to me! Sorry for being slow to reply, I'm in the middle of production, so didn't have time to run this again to confirm and get you a log.

It's great to hear that mayapy should be working. It's probably something on our end that's different from yours. I've tried this again, and as far as I can tell it's whenever there's a walter node in the scene at all that it crashes on open. Removing all walter nodes from a scene will cause it to not crash any more, and an empty scene with nothing but a walter node crashes on open.

We're running Maya2018.3, MtoA 3.0.1.1 and Arnold5.1.1.1 on Ubuntu 14.04LTS (I know, I know. We're moving back to CentOS next month)

Here's the traceback:

pm.openFile("/local/tmp/walter.ma", f=True)
