An important software tool, which was promised for the first time during the release of HoloLens 2 earlier this year, is finally available.
Native support for the Unreal Engine 4 for the HoloLens 2 has arrived via early access to GitHub (login required).  Tim Sweeney, founder and CEO of Epic Games, announced the upcoming development for the first time on the stage of the Mobile World Congress in Barcelona, Spain. However, at the Build conference last month, the world was able to get to know some of the possibilities associated with mating.
Later, the partner manager of Jackson Fields and Epic Games, Chance Ivey, introduced the developers through some of the basics of creating HoloLens 2 apps with Unreal Engine 4.
The package allows streaming support to the PC – Powered Rendering on the HoloLens 1 and 2 for display, and then telemetry and mileage sensor data are returned by the HoloLens to the PC for calculation.
The native support aspect is targeted HoloLens 2 with the XR framework of Unreal Engine 4. After you have created your build on the PC, you can send your build to HoloLens 2 to run it natively on the device. There is no need for a PC. This is useful for users who did not get access to HoloLens 2 so those developers can start building apps in the months leading up to the device's official release.
In addition, voice input is supported. Finger tracking, gesture recognition, fixing of spatial anchors and networking. A production-ready version of the tool, Unreal Engine 4.23, will be released in the next few months.
