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/111184
Unity Compile Error: WindowsXRSimInstallationDetector not found
Hi there, I'm running into an interesting issue on Unity 6.3, using the 83 SDKs. I have installed the simulator, however in my Unity project I get compile errors (and subsequently can't use the simulator) as it seems the script doesn't compile correctly. The following is the error: Library\PackageCache\com.meta.xr.sdk.core@06273138c40d\Editor\MetaXRSimulator\XRSimInstallationDetector.cs(87,29): error CS0246: The type or namespace name 'WindowsXRSimInstallationDetector' could not be found (are you missing a using directive or an assembly reference?) I've tried regenerating project files, reimporting assets and deleting the library folder, everything to no avail. Would be great to get some help regarding this!Issues with Gaussian Splatting integration in Meta Spatial SDK (v0.9.2) – Standalone Quest 3
Hi everyone, I am an architect and urban planner, developing VR/MR projects in my spare time. I’m currently working on a native Quest 3 application to view Gaussian Splats for highly detailed virtual project tours. My Goal: Render native Gaussian Splatting (3DGS) on Quest 3 (Standalone). Synchronize the splat position with the real world for a seamless transition from Mixed Reality (MR) to Virtual Reality (VR) with a skybox. Targeting a minimum of 150k splats with stable performance. Previous Attempts: I initially used Unity with the Aras/Ninja implementations. While it works perfectly via Oculus Link (PCVR), it’s not viable for my needs because: PC Builds don't support the specific MR features I need for this project. The Android build (standalone) performance is extremely poor, even with optimized settings and a small 50k splat PLY file (unusable frame rates). Current Issue with Meta Spatial SDK: I’ve switched to the Meta Spatial SDK (Packages v0.9.2) to leverage the new native splat support mentioned here: Spatial SDK Splats Documentation. Despite following the documentation step-by-step: The splats do not appear in the scene. I am getting several reference errors (MissingReference/NullReference) that I can't seem to resolve. My Question: Has anyone successfully created a native Quest 3 APK using the Spatial SDK to run Gaussian Splats (~150k splats)? If so, could you share the correct workflow or point out common pitfalls with this specific SDK version? Any help or documentation beyond the official guide would be greatly appreciated!
Meta XR Simulator 81.0 is not detected by Unity 6.2
I tried to install Meta XR Simulator as part of Meta All-in-One Package and with Meta Core SDK + Meta XR Simulator standalone setup, all components versioned 81.0 when I'm trying to enable Meta XR Simulator via any of menus where I could do it, I see the same log error every time: [Meta XR Simulator Installer] finished downloading https://securecdn.oculus.com/binaries-download-auth/?id=32431411879837787 [Meta XR Simulator Installer] HTTP/1.1 404 Not Found [Meta XR Simulator Not Installed] Installation failed, please report the issue on the bug tracker. [Meta XR Simulator Not Installed] Try using different version. Open Edit > Preferences... > Meta XR > Meta XR Simulator and choose different selected version. Somehow Unity doesn't detect that Meta XR Simulator is already installed and tried to do it again with an error. My Unity Version: 6000.2.14f1 My OS is Windows 11 Would love to provide any additional information
