Investigation summary

When using the Meta Movement SDK for body tracking in conjunction with the Mixed Reality Utility Kit (MRUK) in Unity, body tracking offsets occur when remounting the HMD. The issue manifests as a misalignment of the tracked skeleton with the user, resulting in distance and angle offsets. This problem does not appear when using the tracking on its own or when the MRUK component's 'Enable World Lock' is turned off, but the latter causes alignment issues between the physical space and virtual objects. The issue is reproducible in a bare-bones project and is documented in the Movement SDK Github repository (issue 130).
