Unity OpenXR Validation Failed on Quest 3 - XR Plugin and Feature Group Fix
Problem: You are building a Unity project for Meta Quest 3 and a check fails with wording like OpenXR validation failed, required OpenXR extension missing, unsupported XR configuration, or Meta’s upload / VRC tooling flags OpenXR before players even install the build.
Quick direction: On Quest, OpenXR is the supported runtime path for modern Unity versions. Validation usually fails because XR Plug-in Management loads OpenXR without the Meta Quest feature set, because competing XR plug-ins are still enabled, or because Android player settings do not match what Meta expects.
This guide walks a clean OpenXR + Quest configuration, verification, and alternatives if you are on an older stack.
Why this happens
- OpenXR is on, but Meta Quest support is off – The loader runs, yet required feature groups (Meta Quest support, controllers, etc.) were never added under OpenXR settings.
- Multiple loaders fight each other – Oculus (legacy) and OpenXR both enabled, or Windows Mixed Reality left on for an Android-only project.
- Wrong build target – Validation is for Android; PC VR settings do not prove Quest compliance.
- Old package mismatch – XR Plug-in Management, OpenXR Plugin, or Meta XR packages are on versions Unity or Meta no longer recommend together.
- Manifest / min SDK drift – Rare compared to feature groups, but very old min SDK or custom manifests can break assumptions in automated checks.
Fix 1 - Reset XR Plug-in Management for Quest (Android)
- Open Edit → Project Settings → XR Plug-in Management.
- Select the Android tab (not PC).
- Disable every provider except what you intend to ship. For Quest with OpenXR, enable OpenXR only.
- If you see Oculus (legacy Android provider) enabled alongside OpenXR, disable the legacy Oculus Android provider unless you are explicitly following a vendor guide that still requires it. Mixed loaders are a common source of validation and runtime oddities.
Verification: Close Project Settings, reopen XR Plug-in Management → Android, and confirm only OpenXR is checked for your Quest shipping path.
Fix 2 - Add the correct OpenXR feature groups (Meta Quest 3)
- Still under XR Plug-in Management, with Android selected, click OpenXR (or OpenXR settings entry—wording varies slightly by Unity version).
- Open OpenXR Feature Groups (or the feature list for the Android build target).
- Enable Meta Quest Support (naming may appear as Meta Quest feature / Oculus Quest in older UI).
- Enable interaction features you actually use, for example:
- Oculus Touch Controller Profile (or equivalent Touch profile) if you use standard controllers
- Hand Tracking only if your app declares and uses it (do not enable unused features that change manifest capabilities)
- Remove or disable features you do not ship (extra extensions can trigger capability mismatches in some validators).
Verification: Make a development Android build, deploy to Quest 3, and confirm the headset enters VR and controllers track. If that works but upload still fails, continue with Fix 3.
Fix 3 - Android player settings that pair with OpenXR on Quest
- File → Build Settings → Android → Player Settings.
- Set Minimum API Level to a level Meta currently documents for Quest (raise it if you are on a very old minimum).
- Use IL2CPP for device builds when that is the recommended script backend for your Unity version.
- Under XR settings (if present as a subsection), avoid conflicting VR SDK lists from ancient Unity—the XR Plug-in Management section is the source of truth on modern versions.
Verification: Build .apk or .aab and install via Meta Quest Developer Hub or adb. Confirm no immediate XR init crash on launch.
Fix 4 - Packages and Unity version sanity
- Open Window → Package Manager, scope Unity Registry (and My Assets if you use Meta’s packages).
- Note versions of:
- XR Plug-in Management
- OpenXR Plugin
- Any Meta XR / XR Core packages your template added
- Compare against Unity’s and Meta’s documentation for your Editor version. If you are multiple major versions behind, update in a copy of the project or read release notes for breaking changes.
Verification: After updates, repeat Fix 1 and Fix 2—package upgrades sometimes reset feature checkboxes.
Fix 5 - Clean rebuild after changing XR
- Delete the Library folder only if you accept a long reimport (optional, last resort).
- More lightly: Reimport XR-related assets or run Edit → Project Settings → XR Plug-in Management → Initialize on load toggles off/on per docs if troubleshooting a stubborn state.
- Create a fresh Android build from Build Settings (avoid incremental oddities).
Alternative fixes
- Legacy Oculus integration – Some older tutorials still reference pre-OpenXR flows. If you must stay on a legacy stack temporarily, match one vendor path end-to-end; do not blend legacy Oculus Android XR with OpenXR without a documented reason.
- PC-only OpenXR – If validation is for Rift / PC OpenXR, switch XR Plug-in Management to the Standalone / Windows tab and configure OpenXR features for PC, not Android. The error text is often similar but the settings screen is different.
- Hand tracking declared but disabled – If hand tracking is enabled as an OpenXR feature but your manifest or store metadata disagrees, some pipelines complain. Align features with actual permissions and store copy.
Prevention tips
- Treat XR Plug-in Management screenshots as release artifacts—save “known good” settings per store submission.
- Pin package versions in Packages/manifest.json via team policy so CI does not drift.
- After any Unity Editor upgrade, run one Quest smoke test before rebuilding submission binaries.
FAQ
Does validation failure always mean the build will not run on device?
No. Some checks are stricter than runtime. Still, treat failures as blockers for store submission until resolved.
Can I use both OpenXR and legacy Oculus on Android?
Usually no for a clean Quest 3 path. Pick OpenXR + Meta feature groups unless documentation for your exact Unity and Meta SDK combo says otherwise.
Where is the exact error text defined?
Wording comes from Meta’s upload / VRC tools or Unity’s XR setup validators. Copy the full message into release notes when asking for support.
