How to carry Extra Attributes on the model when exporting usd in Maya2022?

The Extra Attributes have been prepared in the abc file I made before. After I imported Maya and exported usd, those Extra Attributes disappeared.

This post outlines possible options for exporting custom attributes in general.

You also mentioned alembic and so it would be good for you to explore the AlembicChaser (see docs). One downside currently is that it's only available in the Autodesk plugin after loading the Pixar plugin (so you have to build this repository from sources).

Hope this helps,
