Yes, if you are authoring USD content for Newton physics simulations. The package is lightweight, actively maintained, has no dependencies, and uses a permissive license. However, note that it is in v0.x experimental status—breaking schema changes are possible in future releases, though the maintainers commit to providing migration paths. Requires Python 3.10 or later and a separate USD runtime.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; schemas must be imported before the schema registry is initialized.
- A separate USD runtime must be installed separately.
- Active project with a recent release and no runtime dependencies, making installation straightforward.

What it is and what it does
newton-usd-schemas is a codeless schema package that extends OpenUSD's UsdPhysics specification to support Newton physics engine parameters. It contains no compiled code or public API—instead, it registers schema definitions with OpenUSD at runtime, allowing content creators to author Newton-compatible physics scenes in any USD-capable application without needing the Newton runtime installed.
The package is deployed as a pure Python wheel with zero runtime dependencies, making it lightweight to install. Once imported early in your application, it enables you to apply Newton-specific attributes to USD prims, then export those layers for later loading into a Newton runtime. It follows a minimalist design philosophy, including only attributes with clear physical meaning or cross-solver support, positioning Newton schemas as a staging ground for parameters that may eventually be promoted into the UsdPhysics standard.
Use it for
- Author physics-enabled robots and props in USD-based content creation tools without installing Newton itself.
- Configure simulation parameters in USD layers for later Newton runtime execution.
- Extend UsdPhysics with Newton-specific attributes for multi-solver physics workflows.
- Integrate Newton physics schemas into existing USD pipelines and asset libraries.
- Stage and test physics parameter definitions before proposing them for inclusion in the UsdPhysics standard.
