Hello Strasza,

The extended tracking checkbox is not checked. 

With regards to your other question, yes, I am hiding the button through the function OnTrackingLost(), which is located in the script TrackableEventHandler.cs

This script is checked in the ImageTarget. When I set a breakpoint I confirmed that the app in facts gets into this function. The 3D animation dissapear when the target is lost, except the button. See below:

private void OnTrackingLost()

    {

        Renderer[] rendererComponents = GetComponentsInChildren<Renderer>();

        Collider[] colliderComponents = GetComponentsInChildren<Collider>();

        // Disable rendering:

        foreach (Renderer component in rendererComponents)

        {

            component.enabled = false;

        }

        // Disable colliders:

        foreach (Collider component in colliderComponents)

        {

            component.enabled = false;

        }

        Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " lost");

        mLostTracking = true;

        mSecondsSinceLost = 0;

    }

Thanks,

Marcelo.

Hello marcelof00,

Are you disabling/hiding the button when the target is lost? Do you have extended tracking on?

Thanks,
