ISDK hand tracking issues
I posted this on reddit already. I am having issues implementing hand tracking with Meta XR Plugin and ISDK in UE5.5. Have tried both the ISDK sample project and setting things up from scratch according to the docs. I did it on two different PCs. I am using Virtual Desktop on my Quest Pro. Handtracking inside Horizon Os and VD works perfectly fine. Even when I have no controller in my hand it would show the controller setup. I am able to grab stuff with that crooked hand but pinching does not seem to work, however, I can access the menus by rotating my hand and tabbing. If I set hand tracking to "Hands only", it would neither show hands nor controllers but I can still access the menu using the mentioned gesture. Any idea what is going on here?72Views0likes0Comments
Post-process tint not working with r.Mobile.TonemapSubpass on Quest 3, UE 5.4.4 + Meta XR v71
Hi everyone, I'm developing a VR project for the Meta Quest 3 using Unreal Engine 5.4.4 (official Epic branch, not Meta fork) with the Meta XR plugin v71. I'm running into an issue with controlling tone mapping and applying scene tints using post-process volumes. Issue Summary: I need a post-process volume to adjust tint for a specific area via color grading. I followed the official Meta documentation for tone mapping (link) and enabled r.Mobile.TonemapSubpass=1. Even after disabling all post-process volumes (including those attached to my VR pawn), the scene is still globally tone mapped. When I activate my custom post-process volume, the intended tint effect does not show up. Questions: Is there a reliable workflow for toggling tone mapping, or controlling post-process volume tints (e.g. Scene Color Tint, Color Grading LUT) in a localized area on Meta Quest 3 with Unreal Engine 5.4.4? Are there known engine/plugin bugs or limitations with tone mapping or post-process tint effects when using the Mobile Tonemap Subpass option? Is this issue present in the official Epic branch with Meta XR 71? Are there any recommended workarounds or specific settings to enable area-selective tinting, or a timeline for fixes if this is a recognized problem? Background: I have tested enabling/disabling volumes, used “Infinite Extent (Unbound)”, and tried runtime toggling via Blueprint and console commands. The problem persists both in-editor and on device. Any insight, workaround, or official update from Epic/Meta would be hugely appreciated, as proper localized tint control is critical for my project’s visual design! Thanks in advance!133Views1like0Comments
Meta files that fail on Mac due to hardcoded Windows-style path\filename
Is there a maintained list of Meta UE source files (.cpp/.h) that hardcode Windows-style backslashes in file paths (e.g., path\filename instead of path/filename)? On macOS, those paths aren’t valid and have been breaking packaging/deployment (and sometimes Xcode builds) for me. I’ve confirmed at least two instances and suspect more. A complete inventory would let me verify whether this is the root cause of my Mac build/deploy failures and fix them efficiently.58Views0likes2Comments
ASW + Multiview - UE 5.2 support?
Hi - recently been reviewing our platform settings / features and noticed whilst testing that draws and prims doubled when toggling ASW ON/OFF. It certainly seemed as though multi view was being switched off when running ASW. Struggling to find much info on this relative to whether ASW has multi view support in UE5 let alone 5.2? Any insights would be much appreciated.27Views0likes0CommentsDownload Files the Right Way on Android in Unreal Engine
I came across this blog post from Oculus regarding the proper way to request a download from the Android OS. Here is the article: https://developer.oculus.com/blog/tech-note-downloading-data-in-the-background-on-mobile/?locale=ru_RU I'm trying to download video files on a Quest 2 app built in Unreal 4.26 Oculus Integration version but it isn't as simple as just creating a java. There are a few plugins I've looked but have so far failed to fully implement including : https://github.com/gameDNAstudio/MobileUtils and https://github.com/Sovahero/PluginMobileNativeCode I'm having an issue implementing the Java DownloadHelper class since I can't seem to include the DownloadHelper package with these plugins. Has anyone out there tackled this issue the "recommended" way per the article linked? What would be even better is if Oculus could create a post for Unreal the way they did for Unity! Any assistance would be much appreciated!3.4KViews0likes4CommentsCannot access scene model entities at runtime on UE5.2 / Quest 3
Hi there, I cannot access the scene model which I previously captured using Scene Capture. For my test, I have added the table of my PC workstation. Following the documentation I have added an OculusXRScene actor and configured it. This has definitely worked, as I can see the box shape representing the table when I hit "play in VR". Also, I can see the SceneMesh which I recorded with the depth scanner on the Quest3. When I call GetActorsBySemanticLabel and specify "TABLE" as per the semantic label list on the documentation page, I get zero actors. I am wondering if this is because I use link (for fast testing) but it would surprise me since I can access the scene mesh. Thanks for any hint!!Solved5.2KViews0likes13CommentsUnreal Engine light baking in external editor vs. light buildin in editor for Quest
I have been trying to convert some simple projects to Oculus Quest packages. I am relatively familiar with how light building in Unreal Engine works, but the result looks so different in Vulkan preview mode and on the deployed version that I am wondering if I am doing something wrong. Generally, after baking the lights and switching to Vulkan preview mode, everything looks desaturated and lacks contrast. As a test, I used Blender to bake the direct and indirect light of a scene onto all models, to then use this texture for an unlit material in UE. I was blown away by the quality, which stays almost the same on Vulkan. I do understand that baking lights in the texture using an external editor will look good but will also have several limitations in terms of dynamic lights and shadow casting. What I really do not understand, is why baking lights in UE with production quality settings keep ending up in a massively downgraded Vulkan conversion. Am I doing anything wrong? Do you have any suggestion on the best practices, also related to external software baking? I am using UE4.27.2, vanilla branch from the Epic Games Launcher.2.5KViews0likes1CommentUE5 VRNotificationsComponent issues with Quest 2
Hi, I'm trying to complete all the VRC requirements for app labs and I'm using the latest unreal version 5.3.2 with openXR. But for some reason I can't get the vr notifications component to work in a shipped build (it works in the editor and developer build). Does anyone have/had the same problem or gotten it to work in any shipped build version in UE5. I'm currently thinking about downgrading the engine version to 5.2 again and hopefully that will work.1.3KViews0likes1Comment
Build works in AppLab only when packing everything in one apk (no obb)
Hello, I am using Unreal 5.2.1 with MetaXR 56.0 I managed to make a shipping build and upload it to AppLab with the Meta XR Platform Window (in Unreal editor), but when I launch it in my Quest 2 it just shows the 3 loading dots. The build runs correctly if I install it from my pc using the Install_*.bat in the package folder. If I make the shipping package activating "Package game data inside apk" activated and upload it to AppLab, then it works. However this is not a solution because the apk must be less than 1 GB, and my final app will be more. I also tried uploading from command line, with: ovr-platform-util.exe upload-quest-build --app-id **** --app-secret **** --apk .\MyApp-Android-Shipping-arm64.apk --channel ALPHA --obb .\main.2.com.mycompany.myapp.obb Upload and validation are ok, but when launching the app I still see just the 3 dots. I suspect that the obb file is not correctly managed, because while downloading in the Quest I see that the app size is just the size of the apk (~40 MB), while when downloading the app all packaged in the single apk it was much larger (~400 MB). Thanks for any help!1KViews0likes0Comments
