ovui-widgets Layers Panel

NVIDIA ovui-widgets-layers

1. What is ovui-widgets-layers?

ovui-widgets-layers is the Layers panel distribution of ovui-widgets, the production-shaped scene-widget family built on ovui — NVIDIA's standalone distribution of the Omniverse omni.ui UI framework. It presents a scene's layer and composition stack with full authoring controls, and it runs standalone: no Omniverse Kit installation required.

The panel reads layer and composition data through adapter objects from ovui-data-adapters-common, keeping it independent from the concrete scene backend. It is the Layers panel hosted by the ovui-widgets USD Viewer application and can equally back custom layer-management tools.

ovui is pre-release software and is not enterprise-supported.

2. What functionalities are available, and who are the target users?

What you can do with it:

• Inspect the composition stack — layer order, authoring-target state, dirty/save state, and missing-file signals, with optional prim-spec rows.
• Author the stack — command-backed save, reload, insert, remove, move, merge, and flatten operations.
• Control layer state — mute and lock toggles and authoring-target switching.
• Undo safely — every operation is command-backed and integrates with the shared application undo manager.

Who benefits:

• USD tool & application developers — ship a production-shaped layer editor without rebuilding composition UI.
• Teams with custom backends — reuse the identical panel over any backend that fulfills the layer adapter contracts.

Installation:

python -m pip install ovui-widgets-layers

The panel is normally hosted by the ovui-widgets-app USD Viewer application, which wires it to the shared selection bus, undo manager, and the selected data-adapter provider; it can also be embedded directly in a custom ovui application.

4. System requirements

• Python 3.10+ declared by the wheel; the ovui runtime underneath the widget family requires Python 3.12+
• Linux (Ubuntu 22.04 / Debian) and Windows (Windows 11 / Windows Server 2022), x86_64 — the platforms supported by the ovui runtime
• Declared dependencies: ovui-widgets-common>=0.1.0, ovui-data-adapters-common>=0.1.0
• A concrete data-adapter provider (for example ovui-data-adapters-openusd) supplies the layer data at runtime

---

5. Licensing

• Governed by the NVIDIA Software License Agreement and the Product Specific Terms for NVIDIA Omniverse.
• Source-available for inspection; pre-release versions are provided AS-IS and are not currently open to external contributions.

Note: ovui is pre-release Early Access software and is not enterprise-supported. APIs may change before the 1.0 release.
