Colocation and Shared Spatial Anchors result in wrong frame of reference
Hello everyone! I'm developing a networked experience using Unity 6 with Netcode for Gameobjects and the MetaXR SDK. I am trying to get Shared Spatial Anchors working using Colocation so that the players can see the same frame of reference in Mixed Reality. I managed to get Colocation and Shared Spatial Anchor sharing to work but when I try to align my player rig using the Shared Spatial Anchor from the host there is a misalignment in the scene. No obvious errors or warning are being thrown,I am using the code in the documentation as well as a video tutorial from "XR Dev Rob - Colocation with Meta’s Shared Spatial Anchors & the new Colocation Discovery API" as my main point of reference for my own code. Below is my alignment code if (await unboundAnchor.LocalizeAsync()) { Debug.Log($"Anchor localized successfully, UUID: {unboundAnchor.Uuid}"); var anchorGameObject = GameObject.Instantiate(_anchorPrefab); var spatialAnchor = anchorGameObject.GetOrAddComponent<OVRSpatialAnchor>(); anchorGameObject.name = $"Anchor_{unboundAnchor.Uuid}"; unboundAnchor.BindTo(spatialAnchor); _alignmentManager.AlignUserToAnchor(spatialAnchor); return; } With AlignUserToAnchor(OVRAnchor anchor public void AlignUserToAnchor(OVRSpatialAnchor anchor) { if (anchor == null || anchor.Localized == false) { Debug.LogError("Anchor is not localized yet."); return; } StartCoroutine(AlignmentCoroutine(anchor)); } private IEnumerator AlignmentCoroutine(OVRSpatialAnchor anchor) { var anchorTransform = anchor.transform; for (int alignmentCount = 2; alignmentCount > 0; alignmentCount--) { _cameraRigTransform.position = Vector3.zero; _cameraRigTransform.eulerAngles = Vector3.zero; yield return null; Vector3 offset = anchorTransform.InverseTransformPoint(Vector3.zero); Quaternion inverseYaw = Quaternion.Euler(0f, -anchorTransform.eulerAngles.y, 0f); _cameraRigTransform.position = offset; _cameraRigTransform.rotation = inverseYaw; Debug.Log($"Aligned camera rig position: {_cameraRigTransform.position}, rotation {_cameraRigTransform.eulerAngles}"); yield return new WaitForEndOfFrame(); } Debug.Log($"Alignment complete"); } } I am wondering if I am missing something that needs to be initialized to get the spatial data in order so that the Anchors can get localized correctly. Or if it is something else that I am missing. Thank you for your help! Kind regardsSolved170Views0likes1Comment
