So my reading of this page:

[https://openusd.org/release/api/\_usd\_\_page\_\_multi\_threading.html](https://openusd.org/release/api/_usd __page__ multi_threading.html)

says that I need to do **all** writing to a given stage from the same thread that I opened it on, including calling **.Save()**

Is that true?

It need not be the stage-opening thread, @wave, not even any consistent one … just only one thread at a time, like an stl container.
