PlaneGround floating

May 13, 2018 - 2:23am #1

Hi,

    I put a 3D model on the ground,it is steady. It will float after I shelter the camera like  looking at the wall  or shaking my iPhone hardly.And some error output in Xcode as follows:

NullReferenceException: A null value was found where an object instance was required.

  at PlaneManager.HandleInteractiveHitTest (Vuforia.HitTestResult result) [0x00000] in <filename unknown>:0

  at UnityEngine.Events.UnityEvent`1[T0].Invoke (.T0 arg0) [0x00000] in <filename unknown>:0

The refresh button will help but it could not be as steady as the beginning and this experience is not good for client.How can I fix this issue.
