Unreal Engine 4.21 was released yesterday and it comes with native support for the Windows Mixed Reality platform and headsets. To use this native Windows Mixed Reality support, developers need to run it on the April 2018 Windows 10 update or later, and have a supported headset.
What you’ll need to run Windows Mixed Reality:
- A Windows Mixed Reality head mounted display (HMD).
- A new Windows Mixed Reality ready PC or a Windows Mixed Reality compatible PC running Windows 10 Version 1709 or later.
- Display, USB, and Bluetooth adapters (if required)
- Motion Controllers, an Xbox controller, or a mouse and keyboard
- Headphones with a mic (if your HMD doesn’t have them built in)
- An internet connection
- A large, open space
