MetaXR plugin broken in Unreal Engine 5.4

The MetaXR plugin is broken for the latest on ue5-main branch (commit 7b00eca). Some part of the core VR integration was changed by Epic.  Even though it should all be going through OpenXR.

A beta MetaXR plugin for UE 5.4 would be nice.

    Oh, I see. I thought you mispelled Unreal 5.4 for 5.3. Sorry. I think Meta waits for the official release to update the MetaXR plugin.But I dont know their roadmaps or anything, just a guess.

    I'm using Unreal from Epic version 5.3.2 and MetaXR plugin v60. The project I tested seems ok. What kind of issue did you have?

    I'm working out of the ue5-main branch of the UnrealEngine github repo.  That version is at 5.4.  The MetaXR v60 plugin is broken for that version.

    Its good news when its broken in the main branch tbh, it means someone is doing some typing 🙂

    In their talk on XR Creative Framework, Epic suggested testing the main branch.  So I'm following their guidance.  In general the branch is working well.  The editor builds and runs fine.  Non-VR projects build and run fine.  It's just the OpenXR plugins that are broken.

    You answered your own question.  It is the latest branch.  You need to be patient. Is 5.4 even officially out yet???!!! (I'm pretty sure that's a no...)

    You just need to be patient.

    Meta has pre-release firmware.  They're on v63 now.  I have it installed on my Quest 3.  It's not a stretch for Meta to also start offering pre-release plugins for UE.

    Epic Games has announced a 5.4 deep dive at GDC 2024 next month so hopefully a Meta UE plugin comes in the April timeframe.

    I hear Disney is already using UE 5.4 to target Apple Vision Pro.

      I'm in the same boat. Just waiting for meta to release a beta version for UE5.4

        As UE5.4 officially launched, is there an ETA on the plugin now?

        I'm getting unusable results with VR preview, even just the default VR project freezes everything.

        Tried with wired and wireless, quest link, steam link, virtual desktop, and infuse vr.

            This fork works with 5.4.1 for the impatient like me:

            The release branch is now 5.4.2.  Works fine with latest plugin.  Tested on Quest 3.  I used official Unreal release branch not the Oculus fork

            Ok, works with the standard VR Template, but I still get the same issues with a blank C++ project

            Steps to reproduce:

            1. create a blank C++ project for PC

            2. Enable the plugin & reboot

            3. Select VR Preview.

            All i get is tearing in the device and a frame rate of seconds per frame.

            Has anyone else had better results?
