ARKit face tracking examples crashing on iphone x.

I've got the AR examples running just fine but all the examples that uses face tracking make the app crash instantly. Camera permission are assigned. Any ideas?

 

I'm building for IOS11 with 64 bit support, it has all the permissions, I'm pulling out my hair here.

 

Hey there

We have the exact same problem. Even the test face tracking scenes are crashing. We are on arkit 1.5 and ios 11.3 and its working fine otherwise. Any new info?

Thx Daniel

 

Alexi did you solve? We’re still getting crashes on the face anchor test scene.

 

Nothing? Anyone?

 

'FaceMeshScene.scene' -

I have noticed that the sample scene for mesh face tracking from Unity's ARkit 1.5 crashes when you try to load a new scene after loading one with face tracking enabled. Even when you try to load a blank scene.

Debugging if it doesn't do proper clean up when you load another scene ... any ideas?


libc++abi.dylib: terminating with uncaught exception of type Il2CppExceptionWrapper

 

3 hours later, I've fixed it :

In the file
UnityARFaceMeshManager.cs ( from Unity, in their 1.5 release of ArKit )

Make sure to add this :

Code (CSharp):

1.  
2.  
3. void OnDestroy()
4.     {
5.         Debug.Log("FaceMeshOnDestroy");
6.         meshFilter.mesh = null;
7.         faceMesh = null;
8.     }
9.  
10.  

This performs the proper cleanup that was missing when you go between scenes. :/

 

I had a similar issue when loading a new scene from the Face Axis demo provided in ARKit 1.5 from Unity.

You can't load a new scene after running >> FaceAnchorScene.scene - you will crash the next scene with the error:

libc++abi.dylib: terminating with uncaught exception of type Il2CppExceptionWrapper

To fix, in the file :
UnityARFaceAnchorManager.cs ( from Unity, in their 1.5 release of ArKit )

Be sure to add checks to see if ''anchorPrefab' exists!

Code (CSharp):

1.  
2.  
3. using System.Collections;
4. using System.Collections.Generic;
5. using UnityEngine;
6. using UnityEngine.XR.iOS;
7.  
8. public class UnityARFaceAnchorManager : MonoBehaviour
9. {
10.  
11.     public GameObject anchorPrefab;
12.  
13.     private UnityARSessionNativeInterface m_session;
14.  
15.     // Use this for initialization
16.     void Start()
17.     {
18.         m_session = UnityARSessionNativeInterface.GetARSessionNativeInterface();
19.  
20.         Application.targetFrameRate = 60;
21.         ARKitFaceTrackingConfiguration config = new ARKitFaceTrackingConfiguration();
22.         config.alignment = UnityARAlignment.UnityARAlignmentGravity;
23.         config.enableLightEstimation = true;
24.  
25.         if (config.IsSupported)
26.         {
27.  
28.             m_session.RunWithConfig(config);
29.  
30.             UnityARSessionNativeInterface.ARFaceAnchorAddedEvent += FaceAdded;
31.             UnityARSessionNativeInterface.ARFaceAnchorUpdatedEvent += FaceUpdated;
32.             UnityARSessionNativeInterface.ARFaceAnchorRemovedEvent += FaceRemoved;
33.  
34.         }
35.  
36.     }
37.     void FaceAdded(ARFaceAnchor anchorData)
38.     {
39.         if (anchorPrefab)
40.         {
41.             anchorPrefab.transform.position = UnityARMatrixOps.GetPosition(anchorData.transform);
42.             anchorPrefab.transform.rotation = UnityARMatrixOps.GetRotation(anchorData.transform);
43.             anchorPrefab.SetActive(true);
44.         }
45.     }
46.  
47.     void FaceUpdated(ARFaceAnchor anchorData)
48.     {
49.         if (anchorPrefab)
50.         {
51.             if (anchorPrefab.activeSelf != anchorData.isTracked)
52.             {
53.                 anchorPrefab.SetActive(anchorData.isTracked);
54.             }
55.  
56.             if (anchorData.isTracked)
57.             {
58.                 anchorPrefab.transform.position = UnityARMatrixOps.GetPosition(anchorData.transform);
59.                 anchorPrefab.transform.rotation = UnityARMatrixOps.GetRotation(anchorData.transform);
60.             }
61.         }
62.     }
63.  
64.     void FaceRemoved(ARFaceAnchor anchorData)
65.     {
66.         if (anchorPrefab)
67.         {
68.             anchorPrefab.SetActive(false);
69.         }
70.     }
71.  
72.     // Update is called once per frame
73.     void Update()
74.     {
75.  
76.     }
77.  
78.     void OnDestroy()
79.     {
80.         Debug.Log("Face Axis OnDestroy called");
81.         if (anchorPrefab)
82.         {
83.             anchorPrefab.SetActive(false);
84.         }
85.     }
86. }
87.  

 

Thx guys!

 

Btw: in the latest Arkit are these fixes still neccessary?
Thx
Daniel
