A sample app showing off how to use Image Tracking to track 2 unique images and spawn 2 prefabs for each image. There's also some logic to spawn a prefab between the two images if they are both tracked.
By default the scene has a Missing Prefab in it. This is a prefab from the associated AR Foundation Onboarding UX that you see at the start of the sample video. It is configured to the Find an Image UI with the goal of finding an image. It is not needed to run the sample. You can download the other asset pack and it should be recognized and configured for the scene.
