We tried to reproduce your issue, but it seems to be working for us. Is there enough visual information around the target, so that tracking can pick up the environment? Did this work for you in 8.1, but fails only with 8.2? Can you please share a video of the issue?
we are currently trying to create a scene using Extended Tracking.
However, the function does not seem to work properly. When the camera sees the marker, the Augmented Prefab is correctly spawned, but as soon as the marker is not in focus anymore, the prefab is deleted, as if we were not using the Extended Tracking function.
This is an issue both in our custom scene and in the demo scene coming with the Unity SDK (Image Tracking - Extended Tracking)
