Meta Interaction SDK Version Mismatch in UE 5.7.4 (Requires MetaXR 1.233.0 but found 1.201.0)
I am currently working on a VR project using Unreal Engine 5.7.4 and am running into a version mismatch error between the Meta Interaction SDK and the Meta XR Plugin. The Issue: Upon launching the editor, I receive the following warning: “Meta Interaction SDK version '1.201.0' (v201) requires MetaXR Version '1.233.0' (v201) but found '1.201.0' (v169). Mismatched versions may result in unexpected behavior.” Current Setup: Engine Version: Unreal Engine 5.7.4 (Epic Games Launcher) Meta Interaction SDK: Version 1.201.0 Meta XR Plugin: Version 1.201.0 (reported as v169 by the engine/plugin) Despite both plugins showing as Version 1.201.0 in the Unreal Engine Plugins window, the Interaction SDK specifically requests Version 1.233.0 of the Meta XR plugin to maintain compatibility. Troubleshooting Steps Taken: Verified that both plugins are enabled in the Installed > Virtual Reality section. Updated DefaultBuildSettings to BuildSettingsVersion.V6 and IncludeOrderVersion to EngineIncludeOrderVersion.Latest in my .Target.cs files to ensure they align with UE 5.7 requirements. Attempted to find a standalone download for Meta XR 1.233.0, but the current Meta developer downloads page appears to package them differently. Any help or guidance on how to resolve this version discrepancy so I can utilize the Interaction SDK features safely would be greatly appreciated. Thank you!
Accessing controller input in Meta Quest system UI overlays from custom Android-based engine?
We are building a custom engine on top of Android (using the SDK and Gradle, not Unity or Unreal) porting our products and targeting Meta Quest devices (Quest 3 specifically) for the 2D System panels / overlays (the floating windows in the Quest home environment): What we want: We need to capture *any form of controller input* (buttons, joystick, scroll) while the apps system UI panels are visible or focused. Key constraints: We are not trying to modify system UI, only observe or intercept input Even partial input (e.g. scroll events, pointer movement, or indirect signals) would be sufficient What we’ve tried: Standard Android input APIs (onKeyDown, onGenericMotionEvent) Checking for MotionEvent sources from controllers Polling input devices directly Combed through the SDK without luck Is there any supported way (SDK, API, or lower-level approach) to access or intercept controller input when system UI overlays are active on Meta Quest? Any guidance on how input routing works between apps and system UI on Quest would be helpful.
Record and replay real hand pose at runtime (Meta Interaction SDK – Unreal)
Hi everyone, I’m currently working with the Meta Interaction SDK in Unreal Engine (UE 5.6) and using hand tracking only (no controllers). I’m using the ISDK Hand Rig Component for both hands. What I’m trying to achieve is: I want to capture the user’s real hand pose at runtime, save that pose, and then reapply (replay) that exact pose later on command. So, basically my requirement is, Is there a built-in way in Meta Interaction SDK to record and replay hand poses ? What’s the best way to temporarily override hand tracking and apply a custom pose? Any guidance, suggestions, or pointers would be really helpful. help in any way you can. Thanks.Is there a way to make the player not see their own avatar
Hello, I am building a Unity Project with Meta All-In-One SDK and I'm using the Networked Avatar Building Block on top of Matchmaking and Hand Tracking and Passthrough to create an experience where users can see other avatars with their hand movements with Passthrough in the real world , this creates an effect where you can see people walking around, talking and interacting with things in a room that they are not physically in with passthrough. My issue with this is the fact that the player (host) can see other players' Avatar and other players can see the host's avatar but when the host themselves also look down they also see their own avatar arms connected to their hands and body. I do not really want this Is there way for the player to just see their normal hand prefabs/meshes from their perspective while other connected players see the full avatar and vice versa?Practical Hand Tracking in Unity | Start Mentor Workshop
In this Meta Horizon Start workshop, Start Mentor Valem (Quentin) walks through practical hand tracking in Unity by building and comparing three core interaction models side-by-side: Finger Pinch (including pinch strength values and thresholds) Microgestures (tap + swipes, like an “invisible joystick”) Hand Pose Detection (custom shapes + hand orientation to avoid false matches) You’ll see how to set up a hand-tracking-ready Unity scene quickly using Building Blocks, then implement each input style with simple script patterns and live examples—so you can choose the best interaction method for your own XR app on Meta Horizon OS. This session was recorded in March 2026 as part of the Meta Horizon Start program. 🎬 CHAPTERS 👋 INTRODUCTION 🕒 00:00 - Welcome & workshop goals (comparing 3 hand tracking input models) 📋 PINCH (FINGER PINCH STRENGTH) 🕒 01:10 - What finger pinch is (and why index pinch is most reliable) 🕒 03:05 - Reading pinch strength (0–1) + using thresholds 🕒 05:10 - Interaction SDK examples (grab + ray select) 🕒 07:15 - Build demo: scene setup with Building Blocks + pinch-to-change-color spheres 🕒 10:50 - Smooth vs threshold pinch comparison + reliability notes (index vs other fingers) 📋 MICROGESTURES (INVISIBLE JOYSTICK) 🕒 14:10 - What microgestures are (tap + swipe directions) + use cases 🕒 16:00 - Reading microgesture type in code (switch/cases) 🕒 18:10 - Demo: show detected gesture in TextMeshPro 🕒 20:10 - Note: Interaction SDK locomotion uses microgestures (turn/teleport) 🕒 22:20 - Examples: character movement + UI navigation (and fixing missing EventSystem) 📋 HAND POSE DETECTION (SHAPE + ORIENTATION) 🕒 27:10 - Hand pose detection concepts: shape + orientation 🕒 28:40 - Create a custom Shape (thumbs up) using curl settings 🕒 31:10 - Trigger events when pose is recognized (active state → Unity events) 🕒 33:10 - Fixing thumbs up vs thumbs down: add wrist orientation (Transform Recognizer) 🕒 36:00 - Build thumbs down variant + wrap-up (choosing the right input model) 📚 RESOURCES ➡️ Meta Horizon Developer Forum: https://communityforums.atmeta.com/category/horizon-developer-forum ➡️ Developers Blog: https://developers.meta.com/resources/blog/ ➡️ Meta Quest Developer Hub: https://developers.meta.com/horizon/documentation/unity/ts-mqdh/ 🔗 CONNECT WITH US Sign up to get the latest news from Meta Horizon: https://developers.meta.com/horizon/newsletter 💡 LEARN ABOUT THE META HORIZON START PROGRAM The Meta Horizon Start program provides intermediate and advanced developers with hands-on support and expert guidance to accelerate app development.
