ovui-widgets meta-package: installs all components

NVIDIA ovui-widgets-all

1. What is ovui-widgets-all?

ovui-widgets-all is the aggregate meta-package for ovui-widgets, the production-shaped scene-widget family built on ovui — NVIDIA's standalone distribution of the Omniverse omni.ui UI framework. One install brings in the complete scene-tooling stack — the USD Viewer application, all widget panels, shared services, and the data-adapter contracts plus the OpenUSD provider with a supported standalone usd-core runtime. It runs standalone: no Omniverse Kit installation required.

The package contains no code of its own; it exists so a fresh environment can go from pip install to a working scene application in one step, while the underlying distributions remain independently installable for teams that want only part of the stack.

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:

• Install the complete stack in one step — the USD Viewer application (ovui-widgets-app) with the Stage Browser, Layers panel, Content Browser, Property Inspector, and Viewport widgets.
• Get a working USD backend immediately — includes ovui-data-adapters-openusd with its standalone extra, so the supported usd-core runtime is installed too.
• Run the viewer — ovui-widgets path/to/scene.usda opens the application, or ovui-widgets-headless runs offscreen. The default rendered viewport requires the external ovrtx renderer, which is not installed by this package; with the included OpenUSD provider you can instead opt into its fallback renderer by setting OVUI_WIDGETS_REQUIRE_OVRTX=0.

Who benefits:

• New users and evaluators — the fastest path from an empty environment to a running standalone USD viewer.
• Full-stack deployments — projects that want the entire scene-tooling surface pinned as one coherent set.

Installation:

python -m pip install ovui-widgets-all
OVUI_WIDGETS_REQUIRE_OVRTX=0 ovui-widgets path/to/scene.usda

The one-line quick start above uses the OpenUSD provider's fallback renderer. For the default rendered path, supply the external ovrtx renderer and omit the variable. Kit and custom-USD environments that must retain their own matching pxr runtime should not install this aggregate (it pulls in the standalone usd-core wheel); install the component packages and plain ovui-data-adapters-openusd instead.

4. System requirements

• Python 3.10+ declared by the wheel; the ovui runtime underneath the stack 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, ovui-widgets-app, ovui-widgets-stage, ovui-widgets-layers, ovui-widgets-content, ovui-widgets-property, ovui-widgets-viewport (each >=0.1.0), ovui-data-adapters-common>=0.1.0, and ovui-data-adapters-openusd[standalone]>=0.2.0
• NVIDIA RTX-capable GPU + compatible driver for rendered viewport output via ovrtx; the renderer is not provided by these packages, and the UI, widgets, and headless paths work without it

---

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.
• Installs additional third-party open-source components (for example usd-core) — review their license terms before use.

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