1.16.0

Oculus-1.16 adds support for mixed reality capture (Rift only), which places real-world objects in VR. It allows live video footage of a Rift user to be composited with the output from a game to create combined video that showed the player in a virtual scene. For more information, see Unreal Mixed Reality Capture.

• UE4 Issue - UE4 builds fail when using Android SDK tools 25 or newer. Please review the UE Answers page related to this issue for more information.
