Quest Link Version Mismatch
I updated the Quest Link software this morning and since then handtracking in the Unity Editor doesn't work anymore. Also running the project takes a minute until it starts in the headset - before it only took 1-2 seconds. Last straw I can investigate is this version mismatch. How do I update the headset Link version? At this point I'd like to say to Meta that the developer experience is EMBARASSINGLY BAD and I recommend literally anyone who reaches out to me to not use Quest. Any help would be appreciated.
Voice SDK microphone only starts correctly first time
I'm using the AppDictationExperience component from the Voice SDK in Unity and am trying to play a build on the Quest 2. When I call Activate on the AppDictationExperience component the microphone only starts correctly if the app doesn't have microphone permission when the app starts and asks for permission. If the app already has microphone permission I get an OnMicStartedListening event but the microphone isn't actually recording, if I check Microphone.IsRecording it returns false.
[Unity] Hide or disable hand-tracking logs
Hello, I am seeing thousand of logs like this one in `Android Logcat` window in runtime: 2026-05-05 12:37:37.045 28704 28939 Info InputDevice_Hand HANDTRACKING ADMIRE hand 1: hpm=1 -> shared=0 2026-05-05 12:37:37.045 28704 28939 Info [CT] HandPoseSampler: Filter reset 2026-05-05 12:38:22.126 28704 28939 Info InputDevice_Hand HANDTRACKING ADMIRE hand 1: hpm=1 -> shared=0 2026-05-05 12:38:22.126 28704 28939 Info [CT] HandPoseSampler: Filter reset This appear when using hands and even when using controllers. `Tag Control` can exclude them but then it doesn't show other logs unless I manually add all tags in the list and then deselect these two logs. currently I am using Regex Filter to hide them.🧠Profiling and Memory Deep Dive
Good VR performance starts with knowing where the bottlenecks are, and profiling is more approachable than you'd think. In this session, Meta Horizon Start Mentor Sidney walks through general profiling techniques with a focus on Unity's profiler and memory profiler, Unreal Insights, and automated performance testing frameworks. This session gives you the foundational tools to find performance issues and build profiling into your regular workflow. What you'll walk away with: A practical intro to profiling and how to think about performance in your projects Unity-specific tools including the profiler and memory profiler Unreal Insights and how to use it to identify bottlenecks Automated performance testing so you can catch regressions before they ship
Wit.ai Dictation Request Timing Out
Hi, I've been running into an issue with the Wit.ai dictation service in my Unity VR project and would really appreciate any help or pointers from people who've dealt with something similar. The cofigurations that i'm using as follows: - Device: Meta Quest Pro (standalone mode) - Unity version: 2022.3.x LTS - SDK: com.meta.xr.sdk.voice@69.0.0 What's happening: The microphone starts fine, audio is captured and transmitted without any apparent issue, but the request consistently fails at the point where the server should return a transcription. Here is the error I'm seeing: [VSDK] [SpeechService] [BaseSpeechService.cs:264] Request Failed HTTP Error 503: System.Net.WebException: The remote server returned an error: (503) Service Unavailable. at System.Net.HttpWebRequest.GetResponseFromData (System.Net.WebResponseStream stream, System.Threading.CancellationToken cancellationToken) [0x00146] in <36d5d97f0e39429283d80156f1c7f1fc>:0 at System.Net.HttpWebRequest.RunWithTimeoutWorker[T] (System.Threading.Tasks.Task`1[TResult] workerTask, System.Int32 timeout, System.Action abort, System.Func`1[TResult] aborted, System.Threading.CancellationTokenSource cts) [0x000f8] in <36d5d97f0e39429283d80156f1c7f1fc>:0 at System.Net.HttpWebRequest.EndGetResponse (System.IAsyncResult asyncResult) [0x00020] in <36d5d97f0e39429283d80156f1c7f1fc>:0 at Meta.WitAi.WitRequest.HandleResponse (System.IAsyncResult asyncResult) [0x00034] in .\Library\PackageCache\com.meta.xr.sdk.voice@69.0.0\Lib\Wit.ai\Scripts\Runtime\WitRequest.cs:633 Request Id: 1777907594-580491d1-b43e-4335-8900-4001fba36b2d [1d5ec5c8-9c59-4de2-9c01-256ea3d2135a] === STACK TRACE === One thing worth mentioning: this service has been working reliably in my project for a long time with no code changes on my end. The issue started appearing on April 22nd out of nowhere, which makes me think something may have changed on the service side rather than in my setup. Any suggestions would be much appreciated — thanks! Tonglin
Unity GUID collision
Hello! The XR Core SDK uses GUID `a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6` in file Scripts/BuildingBlocks/AIBlocks/Transport/StreamingParser.cs.meta, which looks suspiciously like a placeholder someone typed in. It turns out that mcl-unity uses the same GUID, leading Unity to endlessly complain about GUID conflicts if you import both packages. I reported it to that project but given that two people independently typed that GUID in, it seems likely that there are more instances of it out there. Any chance you could regenerate the GUID please?
