Changelog Description
Workaround default prim bug in Maya 2025.3 with Maya USD 0.30.0
See: Autodesk/maya-usd#3991
Additional review information
Without this fix the published USD file will not be loaded correctly when referenced. This is e.g. noticable when using the AYON USD contribution workflow and the model is 'missing' when loading the asset USD file. This is because the generated file itself lacks correct default prim metadata due to the Maya USD regression/bug.
Testing notes:
Or simpler, but maybe more technical for some. Confirm the actual written
defaultPrimvalue in the written USD file is not prefixed with a|.
