# USD Validation NVIDIA Notices

## Project License

USD Validation NVIDIA is provided under the [Apache License, Version 2.0 and Creative Commons Attribution 4.0
International Public License](LICENSE).

## Runtime License Notices

These licenses pertain to the USD Validation NVIDIA Python packages built from this
repository.

OpenUSD uses many 3rd Party OSS to build and at runtime. Most of these are isolated to individual modules
(USD plugins). Many are only relevant to a rendering context (e.g. via Hydra) and do not apply to a 3D scene
description authoring context.

This repository does not use or redistribute generated `usd-deps` license files. The individual license entries below
therefore link to the upstream projects directly.
