Title: OpenXR Runtime Missing on ML2 → Plane Detection & Spatial Mapping Not Working (Only Stub Runtime Loaded)

Body:

Hi everyone,

We are currently unable to get plane detection working on Magic Leap 2 when using Unity OpenXR. The app builds and runs, but no planes or spatial mapping data are ever returned, and the system appears to fall back to a stub OpenXR runtime instead of the actual Magic Leap OpenXR runtime.

Environment

  • Unity Editor: 6000.1.17f

  • Magic Leap 2 OS: 1.12.0

  • MLSDK: 2.6.0-pre.R15

  • Unity XR Plugin: OpenXR + MagicLeap OpenXR Features enabled

Problem

When ARPlaneManager / meshing subsystems attempt to start, the following log appears repeatedly:

OpenXR-Loader:
getActiveRuntimeCursor: Querying URI: content://org.khronos.openxr.runtime_broker/openxr/1/abi/x86_64/runtimes/active
Failed to find provider info for org.khronos.openxr.runtime_broker

Got runtime: package: , so filename: libopenxr_runtime.magicleap.so, native lib dir: /system/lib64, has functions: no

Later:

Runtime Name: MAGICLEAP
Runtime Version: 1.0.7
Runtime extensions enabled: (26)

This strongly suggests the headset is initializing the OpenXR loader, but the actual runtime package (com.magicleap.openxr) is missing, so the loader falls back to /system/lib64/libopenxr_runtime.magicleap.so, which contains no spatial mapping or plane detection functionality.

Observed behavior

  • ARPlaneManager.trackablesChanged fires with only 1-2 planes, then only updates

  • No plane meshes are ever visualized

  • Meshing providers fail with RuntimeFailure

  • Anchors and Scene Understanding calls also fail

What we have tried so far

  • Verified Unity OpenXR settings + MagicLeap feature configuration

  • Confirmed AR Plane Manager & AR Camera setup is correct

  • Reinstalled the OS

  • Checked package list via adb shell pm list packages | grep -i openxr

  • Only found:

    com.magicleap.openxr_runtime_broker

    → missing: com.magicleap.openxr

  • Reinstalled MLSDK, Unity packages, and rebuilt project

Key Question

Should com.magicleap.openxr be present as a system package on ML2 OS 1.12.0?
If yes — this seems like an OS-side installation issue, not a Unity configuration issue.

Before we proceed with a full factory reset, we want to confirm this diagnosis.

Any guidance or confirmation from Magic Leap engineers or anyone who experienced similar behavior would be greatly appreciated.

Thanks!

In your configuration do you have the OpenXR Magic Leap provider enabled and the legacy MLSDK provider disabled. (Make sure you do not have the com.unity.xr.magicleap package installed unless you are using MLSDK) Otherwise you will only need the openxr package.

Are you requesting the correct spatial mapping permission when the application starts?
