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
