Hi,
If you look in your 4.21 install under Engine\Plugins\Editor\USDImporter\Content\Python\usd_unreal, you’ll find a few files.
- test.py shows a standalone example of how to use the Python API to do various import and export tasks.
- You can also look at the init_unreal.py file (and the other modules it relies on) to see how level import and export are hooked in to the Editor UI when the plugin is loaded and at editor startup, and how those functions are implemented.
I think that’s what the feature description is referring to, and I’m reaching out internally to check if there’s anything else.
