A quick primer on OpenXR
OpenXR is an open-source standard that defines an interface between XR apps and platform runtimes. The OpenXR specification contains two categories of features: core features, which are present on every platform, and extensions, which are optional and may not be implemented by some platforms.
Unity's OpenXR Plug-in integrates core features, while this package integrates Meta-specific vendor extensions. Refer to Architecture for a full list of OpenXR extensions that this package uses.
Requirements
To use Unity OpenXR: Meta, your project must meet the following requirements:
- Unity 2022.3 or newer
- AR Foundation 5.1.0 or newer
- OpenXR 1.7 or newer
When you install this package, if you don't already have AR Foundation or OpenXR in your project, the Package Manager will automatically install these dependencies.
