META Quest Crash on load
I have an Unreal 5.5.4 build of my game that was previously working, unchanged and now I can't get it to load. It immediately crashes after load screen and I am struggling to understand from the log why. seems to be related to this but dont really understand what is happening. Can anyone help? this is filtered to show only outputs from my game (DontMove)
Integration for Unreal Engine 5.6
Hi, I'm trying to build a game with mixed AR in UE5.6 but everywhere I look it says I need to download the UE5 integration plugin from this link: https://developers.meta.com/horizon/downloads/package/unreal-engine-5-integration/78.0 The thing is I see it goes up only up to version 5.5 for UE5 and no version for 5.6 (I also can't downgrade my project's version). Anyone knows when can I expect a new version for this plugin to match UE5.6?Casting And Recording Issue
I've been trying to record or cast my unreal engine project, but been unable to do so as in both scenarios the project runs as it's supposed to through the headset itself but is unable to be seen through the video or the casting. Through the cast I can hear the sounds within the project as it's played but I'm unable to see the app itself and same with the video recording. If anyone knows a workaround to be able to see the project being played while casting and recording it would be much appreciated.
Avatars SDK for UE 5.6?
Hello, We are developing a VR experience in which people can meet in a virtual space. Using Meta Avatars would be great for optimisation purposes (compared to MetaHumans). If that's not possible, what VR character models are you using? The robot mesh with no legs in the Collaborative Viewer Template isn't ideal for our purposes. Ideally, we would like human characters with different hair colours, arms, legs and outfits.
Landscape flickering / tearing near player when Multi-View is enabled (UE 5.5.4 + Meta XR)
Hi everyone, I’ve been debugging a strange rendering issue for weeks and finally narrowed it down to Mobile Multi-View. Setup: Unreal Engine 5.5.4 Oculus Fork Meta XR Plugin v78 Quest 3 The problem: When Mobile Multi-View is enabled, my Landscape shows “cracks” and flickering holes near the camera — almost like the sky leaks through the ground. The issue: Happens only near the player. Far away, the landscape looks perfect. Disabling Mobile Multi-View fixes it instantly. It happens both in Vulkan Mobile Preview and on the actual Quest 3 build. Material complexity doesn’t matter, even a flat opaque color shows the same behavior. I’ve tested: Rebuilding the landscape (even a new one). Forward Shading, no Nanite, no Virtual Textures. CustomDepth off, no post-process volumes, near clip plane 20cm. The issue only disappears when Multi-View = false Has anyone else seen this? Appreciate any help. Thank you!
Unreal Passthrough camera support plugin
I just released a (paid) plugin for easy and fast camera access in Unreal, which has support for Quest 3 passthrough camera access, including accessing both cameras at the same time. It is possible in theory to access one camera in Unreal using the built in camera plugin, but (a) it is slow and inefficient, (b) it won't let you access multiple cameras, and (c) my plugin gives you a simple, supported way of accessing the cameras, including handling permissions and getting textures directly to GPU rather than loading them via memory.
