Description of the issue:

Hi, since I updated Lightship to the new version I’m having problems with the AR Tracked Image Manager provided by ARFoundation.

Found the target doesn’t work with Lightship sdk + Google AR Core, but works with only Google AR Core.

Furthermore in the Lightship ARDK 3.0 has a Image Target for the Shared Space Manager, but no one for the experience without sharing.

There is bug about this? Or this feature is not implemented in the new ARDK?

I’m trying to use the SharedSpaceManager to create a ImageTarget.

This is my code:

private void OnEnable()
        if (_sharedSpaceManager == null)
            _infoDebug.text = "Sto aggiungendo lo SpaceManager\n";
            _sharedSpaceManager = GameObject.FindAnyObjectByType<SharedSpaceManager>();
            _infoDebug.text += _sharedSpaceManager != null ? "Aggiunto" : "Fallito";

        _sharedSpaceManager.sharedSpaceManagerStateChanged += OnColocalizationTrackingStateChanged;


    private void OnDisable()
        _sharedSpaceManager.sharedSpaceManagerStateChanged -= OnColocalizationTrackingStateChanged;

    public void generateShareExperience()
        var imageTrackingOptions = ISharedSpaceTrackingOptions.CreateImageTrackingOptions(
                    _targetImage, _targetImageSize);
        var roomOptions = ISharedSpaceRoomOptions.CreateLightshipRoomOptions(
            "image tracking colocalization demo"

        _sharedSpaceManager.StartSharedSpace(imageTrackingOptions, roomOptions);

 private void OnColocalizationTrackingStateChanged(SharedSpaceManager.SharedSpaceManagerStateChangeEventArgs args)
        _infoDebug.text = "Qualcosa accade";

        if (args.Tracking)
                   _sharedSpaceManager.SharedArOriginObject.transform, false);

But also in this case when I frame the target with the device, nothing happens

Hi Extesa,

I’m sorry to hear you’re having trouble using image tracking with Lightship. When you say it wasn’t working, were you receiving an error message? If not, could you please test again with development mode enabled and your device connected to your development computer to read output?

Kind Regards,
