A scene is a group of objects positioned relative to a ‘trigger’ image. When a user scans the trigger image the scene objects will appear on top of the trigger, just as they appear in the editor.
Scenes can contain animations and videos that will start playing when the user first scans the trigger. If the user stops scanning the trigger all animations will pause, and restart next time the user resumes scanning.
You can add buttons that allow you to navigate between scenes while still looking at the same trigger. Check out the ’Scene Editor - Button’ article to see more on this advanced technique.
