GeoExport

The GeoExport node exports a flattened stage to a file. You can export USD files using the .usd, .usdc, and .usda file extensions.

Note: Writing the whole flattened stage is not a common workflow unless you are creating a stage from scratch with Nuke nodes.

Tip: GeoExport's classic 3D system equivalent is the WriteGeo node.
