VR Preview not syncing with Meta Quest 3 in Unreal Engine 5.6.1

Development Programming & Scripting

  • Unreal Engine: 5.6.1

  • Device: Meta Quest 3

  • Connection: USB 3.0 via Meta Link (working fine in PC app)

  • Project Type: VR Template (newly created project)

When I first created the project using the VR Template, the “VR Preview” option was greyed out.
After enabling Meta XR Plugin and Meta XR Platform Plugin, the VR Preview button became clickable — but when I press it, Unreal enters “Preview mode” on the PC monitor (as shown in the attached screenshot), yet the headset does not display and sync with the preview.

The headset stays in the default Link home environment and doesn’t mirror what’s in the Unreal viewport.

What I’ve Tried

  • Confirmed that Meta Link is connected and working (can run PCVR titles normally).

  • Enabled both Meta XR and Meta XR Platform plugins.

  • Restarted Unreal Engine and the headset after plugin activation.

  • Tried both “VR Preview” and “Play → VR Preview” from the toolbar.

Still, the headset does not show the Unreal scene — only the PC monitor preview works.

Question
What else do I need to configure to get VR Preview working and synced with my Meta Quest 3 in Unreal 5.6.1?
Any specific configuration steps or Meta XR Plugin settings I might be missing?

I assume you have already enabled developer mode on the Quest and executed the MetaXR Project setup tool of the plugin. You should also check whether the developer runtime functions are enabled in the settings of the Quest Link app.

Thank you for your answer, and yes, I’ve enabled developer mode and executed the Meta XR Project setup tool, and I don’t have any red alarm throughout the whole project setting. Also, developer runtime functions are enabled too.

I have only observed that issue with the VR preview in the following cases - if the option “Start in VR” is not checked in the project settings, if thee is an issue with the Meta Quest Link app, or if the Meta Quest Link is not set as the active OpenXR Runtime.

But, there could also be something wrong with the editor installation. Did it work with a previous version of Unreal and do you have the option to test that?

VR Preview not syncing with Meta Quest 3 when Meta XR plugins are enabled (UE 5.5)

I am experiencing the same issue described in this thread and have not found a solution yet.

Setup

  • Unreal Engine 5.5

  • Meta Quest 3

  • Connection via USB using Meta Link

  • Developer mode enabled (Meta account and headset)

Problem

  • When Meta XR Plugin and Meta XR Platform Plugin are disabled, VR Preview works correctly and the Quest 3 mirrors the Unreal scene.

  • When these plugins are enabled (which I need for my project), VR Preview starts on the PC monitor only.

  • The headset stays in the Meta Link home environment and does not sync with Unreal.

What makes this confusing is that the exact same project works on my colleague’s machine with the Meta XR plugins enabled.

What I have checked / tried

  • Meta Link connection works, PCVR apps run fine

  • Developer mode enabled

  • Meta XR Project Setup Tool executed, no errors or warnings

  • “Start in VR” enabled in Project Settings

  • Meta Quest Link set as the active OpenXR runtime

  • Developer runtime features enabled in the Meta Link app

  • Restarted Unreal, Meta Link, and the headset multiple times

Question
Are there any additional settings, OpenXR runtime options, or Meta XR plugin configurations that could cause VR Preview to only render on the PC while the headset remains in Link Home?

Any insight into differences between machines where this does work would also be very helpful.

Thanks in advance.
