I want to make an object to disappear when one of my Image Marker is matching and when other Image Marker is recognized that object to be visible again (is a button on my canvas). I've tried to that using those functions : OnMatchAcquire and OnMatchLoss , but only first one is called and when i put my camera on the second Image Target first Image Target is still recognized. Here being the second problem. How to reset those conditions when one Image Target is recognized other to be not. Thanks for help!
