Question AR Foundation Image Tracking doesn't work with 2 Scenes

Hello,

I have two different Scenes where I want to use the Image Tracking. When I change to the Scene the first time everything works fine, but when I come back to the Scene again (with SceneManager.LoadScene) the trackedImagesChanged doesn't reach the eventArgs.added instead directly the updated one. Shouldn't it be that these events get deleted when I change a Scene? I also tried to destroy the ArTrackedImageManger before I change the Scene but without results. In AR Foundation 2 and Unity 2019.2 the problem didn't occur. Now I changed to AR Foundation 4 and Unity 2019.4 and this happens. I am testing it on iOS.

 

Try to call LoaderUtility.Deinitialize() after scene unload and then LoaderUtility.Initialize() when you load new scene.

 

thank you, it solved my problem
