I am developing an app where the user has to switch between AR mode and normal mode and is using user defined marker. The app starts in normal mode and the switches between normal and ar mode. The first time the user scans the marker, it works correctly but after that when the user switches from AR mode to normal mode and then back to AR mode, when the user tries to scan for a marker it always give the error that the image quality is poor - this happens even if it is the same marker that was used in the first scan.
When I switch from the AR mode to normal mode, I disable the camera object as well as call Vuforia.VuforiaBehaviour.Instance.enabled = false.
Any idea how to fix this issue?
