Overview#

USDZ Exporter packages assets into a USDZ archive, making it easy to export scene layers for sharing or further processing. The extension adds a context menu to layer window for easy access. It offers a straightforward API to trigger exports asynchronously.

Functionality#

usdz_export(identifier, export_path): Asynchronously exports a specified layer to the provided file path. It gathers required files in a temporary directory before packaging them into a USDZ archive.

Relationships#

Depends on modules like omni.kit.window.file_exporter to provide a consistent file export experience.
Utilizes omni.usd and omni.usd.libs for handling USD data structures during the export process.
Integrates with omni.kit.usd.collect to aggregate assets for packaging.
Works alongside omni.ui and omni.kit.pip_archive to manage user interface components and dependency delivery.

Considerations#

The usdz_export actions are only active when layer functionality is available, ensuring that the LayersMenu is only added when the “omni.kit.widget.layers” extension is loaded.
The extension adapts dynamically to workspace changes, creating or cleaning up its UI components on startup and shutdown.
Its simplicity and clear API design facilitate integration into script-based workflows within the Omniverse Kit SDK.
