Epic Games has now released Unreal Engine 4 support for the Microsoft HoloLens 2 in early access. The early access support is live on GitHub, giving developers access to APIs for the platform’s unique features. Production-ready support for HoloLens 2 will ship in Unreal Engine 4.23, due out this summer.
The latest documentation is on GitHub and an introductory talk from Microsoft Build provides information on common development tasks. The new Windows Mixed Reality sample project, shown at Microsoft Build, is also available for download.
