I tested out with these two options and also do some research on the mayaUSD. It seems that these two options haven't been exposed to Python as it errors out in maya 2025.1 during extraction.

That's odd. But they are in the list here: https://github.com/Autodesk/maya-usd/blob/dev/lib/mayaUsd/commands/Readme.md#mayausdexportcommand

Can you check which maya-usd addon version you're using?

I am at 0.28.0 not the latest 0.30.0. That could be the reason. I would download the latest version and try it again.

Thanks - yes. Seems added in 0.29.0 -> https://github.com/Autodesk/maya-usd/blob/v0.29.0/doc/CHANGELOG.md

Will take it into consideration. 👍
