Unity Technologies has released a new Unity XR Hands package containing a number of new tweaks and improvements as well as enabling and tracking with OpenXR. Released as a package for the developer and cross-platform game engine Unity, the latest edition allows developers to add hand tracking without using headset-specific SDKs.

Launched as a preview, XR Hands supports virtual reality hand tracking through Unity's standard XR subsystem and OpenXR. Allowing it to support other systems such as the XR Interaction Toolkit. Unity also hopes to add support for other OpenXR headsets whose hand tracking already supports Meta Quest and Microsoft HoloLens systems.

"This package will work with OpenXR if the OpenXR package is installed and used. To see if other vendor plugin packages you are using support manual tracking, check the documentation for those packages .

A sample viewer is provided and can be imported into your project via the Samples tab of this package's view in the Package Manager window.
