Maya: bug switching sub-assembly representation from Full to Collapsed about openusd HOT 4 CLOSED

Filed as internal issue #137727.

from openusd.

I just checked and the solution from issue #61 of setting the root primPath work here as well:

import maya.cmds as cmds
root = cmds.assembly(name='testAss', type='pxrUsdReferenceAssembly')
cmds.setAttr(root + '.filePath', '/projects/usd/tutorials/endToEnd/models/Room_set/Room_set.usd', type='string')
# Must set primPath!
cmds.setAttr(root + '.primPath', '/Room_set', type='string')
cmds.assembly(root, active='Expanded', edit=True)
sub = 'NS_testAss:Ball_1'
cmds.assembly(sub, active='Full', edit=True)

I think both of these issues are now a question of how best to prevent users from making this mistake. Some options:

• finish the "Create -> Scene Assembly" menu in Maya and enforce the automatic setting of primPath there. Right now all it does is make the assembly node with no attributes set.
• add an explanation of the modes and how to setup the assembly node to the docs
• change the behavior: It's somewhat inconvenient to have to manually set the primPath to the defaultPrim, and it's not intuitive that not setting it would invoke an alternate mode which breaks nested assemblies. So from my limited point-of-view it would be good to have the default behavior (omitting the primPath) be one that works, while having the alternate mode be something that is more explicitly enabled. but like I said, I'm not sure what the purpose of the alternate mode is, so that may be a misguided suggestion.

Hey @chadrik - we think the work by @mattyjams to make nested assemblies pull from the main stage also addressed this (we can no longer repro)... and you're also no longer interested in assemblies :-) Closing!

roger. you can probably close #61 too
