Hi, i need help. I use unity2018.2.12f1&Vuforia 7.5.26. My task - dont hide object, after image doesnt in FOV. I made track device pose, positional mode, optimize for images and deleted code OnTrackingLost(). It works incorect. When status is NOT_FOUND camera does not see the model but model did not dissappaer. You can watch that in video

You maybe incorrect understand my question. I don`t need disabling augmentation when my image == EXTENDED_TRACKED. How i can make this?

1. Ar camera found image target and create object

2. When i remove my image from camera (in real world) my object didnt dissapear.

3. I can rotate device, i can walk arround and my model stay at that position when first spawned, even my target was lost at 5 min ago

i have problem with that. When my image lost tracking(no pose, not found etc.) my camera (AR camera) broke. Object didnt destroy, but camera didnt see him

My guess is that Extended Tracking may be enabled in your project (aka Positional Device Tracker): Unity Editor->Window->Vuforia Configuration->Device Tracker->Track Device Pose

Try testing for a target's state as "EXTENDED_TRACKED", disabling the augmentation if your target is in that state.
