SteamVR OpenXR Runtime with Oculus Devices

We are having an issue with OpenXR compatibility between Oculus devices (Quest 2) and the Steam OpenXR Runtime. We have built our application in Unreal 4.27.2 with the OculusVR plugin and have set the XR API setting to OVRPluginOpenXR. We are also including the SteamVR and OpenXR plugins in this same build to support SteamVR devices.

 

We are launching this build from Steam and are seeing the following behaviour:

  • Oculus devices work over SteamVR when the default OpenXR runtime is set to Oculus OpenXR
  • Steam devices work over SteamVR when the detault OpenXR runtime is set to Steam OpenXR
  • Oculus devices do NOT work over SteamVR when the default OpenXR runtime is set to Steam OpenXR

 

In the last situation, the application starts in flat screen mode and does not start in the HMD. What is the correct configuration of plugins and OpenXR API settings to support all three of these cases in one build?
