Can Meta XR SDK build for Windows PC VR, or is it Quest-only?
I've been developing a VR game for Quest Pro/Quest 3 for the past year using Unity 6 (6000.0.40f1) with Meta XR SDK (Core 74.0.1, All-in-One 74.0.2, Interaction SDK 74.0.2, Essentials 74.0.1). Current situation: Standalone Quest APK builds work functionally Performance is poor (~40-50 FPS, pixelated visuals) Unity Editor with Quest Link runs beautifully (80+ FPS, crisp visuals) What I need to know: Can I build a Windows platform executable with Meta XR SDK and run it as a PC VR app via Quest Link? Or is Meta XR SDK strictly for standalone Quest Android builds? What I've done: Optimizing the standalone build with my own code logic and texture compression, and logging disabled (My game has a server logging feature) Limited improvement due to an asset-heavy project Why I'm asking: Since Quest Link (Editor to Quest) performs so well, I'm wondering if I can build a Windows .exe that runs the same way - using my PC's GPU while the Quest acts as a display/input device. Constraints: I need Meta XR SDK specifically for eye tracking (Quest Pro) Not using OpenXR due to reported conflicts with Meta XR SDK Has anyone successfully built Windows PC VR apps using Meta XR SDK? Or is the SDK Android-only, requiring a switch to OpenXR/SteamVR for PC builds? Any guidance or documentation links appreciated! Other questions: Does eye tracking work over Quest Link with Windows builds? Are there specific build settings or plugins needed? Any performance differences vs standalone?🚀 Social VR Accelerator Orientation
Build and launch a Social VR game in 4 weeks. This isn't just a class, it's an accelerator. You'll start with a Unity template, get weekly mentor support, test with real players, and launch on the Meta Horizon Store by Week 4. To get started, all you need is beginner experience with C#, Unity, or the Horizon World Editor, plus 1–4 hours per day on weekdays. Apply as a team (designer + developer) or solo. This invite is open to Meta Horizon Start Members. In this session, we'll walk through how the 4 weeks work, what's expected each week, and how mentorship and playtesting are set up. You'll get access to your Unity starter template, set up your dev environment, and meet the other teams. What we'll cover: Program timeline and weekly milestones Mentor and check-in structure Starter template walkthrough Team introductions How to get help along the way By the end of orientation, you'll know exactly what you're building toward and how to hit the ground running in Week 1.

Cannot set Meta Quest Link as active OpenXR runtime normally
Hello! We are developing a PC-VR app in Unity with Meta Quest 3 at our company. We use OpenXR plugin to build the code around OpenXR standard in order to support more platforms in the future. However, the button to set the meta quest link as active runtime for open xr never works on our test PCs. We've tested multiple laptops & PCs in the companies and none of them seem to be work without us manually setting the path in the registry. We've tried starting the Link app as an admin, installed it as an admin etc. One time the registry entry doesn't even get added automatically after installing Meta Quest Link App and we had to install "OpenXR for Windows Mixed Reality" to create it without writing a script to automatically create the group entry ("HKLM\Software\Khronos\OpenXR\1") in the registry. Could anyone help clarify what is up with this case and how we can resolve it? Otherwise the setup process is basically impossible for our potential customers without in-depth technical support... Thank you! References: https://community.khronos.org/t/openxr-directory-not-existing/111184Unified Social Sharing Between Facebook and Instagram
Dear Meta Product Team, I hope you are doing well. My name is Veeranna Angadi, and I would like to share a product idea that could significantly improve user experience across your platforms. Currently, users actively engage with both Facebook and Instagram, but they are still treated as separate ecosystems when it comes to social sharing. For example, if a user enjoys a reel on Facebook and wants to share it with their Instagram friends, the only available option is sharing via a link. This creates friction and reduces seamless engagement. Proposed Idea: Unified Social Graph & Cross-Platform Sharing I propose introducing a feature that allows: Integration of Facebook friends and Instagram followers into a unified social layer (with user consent and privacy controls) Direct sharing of content (reels, posts, stories) across both platforms without needing external links Optional “Cross-Platform Audience” selection while sharing content Smart suggestions (e.g., “Share this reel with your Instagram close friends”) Benefits: Increased content engagement and retention within Meta platforms Reduced friction in content sharing Stronger ecosystem integration between Facebook and Instagram Improved user satisfaction and time spent on apps Additional Enhancement: A recommendation engine could identify which platform a user’s friends are more active on and suggest optimized sharing for better reach. I believe this idea aligns with Meta’s vision of building connected experiences across platforms. If this idea is considered valuable, I would appreciate recognition or the opportunity to collaborate further. Thank you for your time and consideration. I would be happy to discuss this idea in more detail if required. Warm regards, Veeranna Angadi Bangalore, India
HelloWorld & Basic Sound tutorials
Hello, hoping somebody has an answer for this. I've been trying to get this basic voice input working and have been running into an issue. https://developers.meta.com/horizon/documentation/unity/unity-tutorial-basic-voice-input/ https://developers.meta.com/horizon/documentation/unity/unity-tutorial-hello-vr/ The issue is I receive and error that says... Script 'CharacterController' has the same name as built-in Unity component. AddComponent and GetComponent will not work with this script. Both meta and unity have a CharacterController. I have been unable to get around this as I need the AddComponent and GetComponent to work. I can't be the first person to come across this; particular when its in a hello world example and yet I can't find any information on it. Help would be appreciated. Thanks
Firefighter learning VR/AR Advice???
To: Any Available VR/AR Developer, My name is Kyle, and I’m an ARFF firefighter interested in learning AR/VR development to help create better, more realistic training tools for the fire service. Since few firefighters develop—and few developers have been on a nozzle—I think I can bring a useful perspective. I’m reaching out to this Meta forum because this is exactly the kind of place I think I could get good advice. I’d appreciate any advice on: Where to start learning, Which skills matter most, What can I skip early on, and your view of the current AR/VR firefighting training market. Thanks for your time, Kyle
