I tried with VR template in UE5.5.4
If I set MetaXR\XRAPI → Oculus OVR Plugin, I can’t run the preview and got bug

LogOVRPlugin: Display: Unavailable OpenXR extension: XR_EXT_future
LogOVRPlugin: Error: [XRCMD][failure] [XR_ERROR_EXTENSION_DEPENDENCY_NOT_ENABLED]: xrCreateInstance(&createInfo, &instance), arvr\projects\integrations\OVRPlugin\Src\Util\CompositorOpenXR.cpp:4417 (arvr\projects\integrations\OVRPlugin\Src\Util/CompositorOpenXR.h:350)
LogOVRPlugin: Display: Initialize: xrCreateInstance() failed
LogOVRPlugin: Error: Plugin failed to initialize. (arvr\projects\integrations\OVRPlugin\Src\Util\CompositorOpenXR.cpp:2739)

If I set MetaXR\XRAPI → Epic Native OpenXR, it could run. But the hand tracking didn’t work (only the controller tracking worked)
How could I fix it?

Meta has very limited support for OpenXR extensions in the Link/Airlink runtime, and most of them are limited to developer mode. Practically all their features beyond the basics are only designed for native applications running on the headset.

I saw this tutorial working well. Hope to find the correct setting :frowning:

The important setting would be the Developer Runtime Features in the Meta Link settings. Also make sure you are actually using Meta Link or Airlink to connect to the PC, and not another runtime like Virtual Desktop or SteamLink.

That error doesn’t have nothing to do with Hand tracking. it happen when you open Unreal before enable Link or Air link. Sometimes that error show up for no apparent reason.
Make sure you have this enabled.

All settings is correct. After update Meta link, the error bug has gone, but still can’t connect to HMD
LogOVRPlugin: Display: OpenXR runtime name: Oculus, version 1.110.0
LogOVRPlugin: Display: OpenXR runtime supports XR_META_headset_id extension
LogOVRPlugin: Display: xrGetSystem() failed, which might be caused by a temporarly HMD connectivity issue. xrInstance to be destroyed
LogHMD: Failed initializing OVRPlugin 1.109.0

I think I found the way to fix it through the following link
