Is it possible to set up an image tracking scene to allow for the tracking of the same marker at different physical sizes? I know with plugins such as Vuforia you are able to scan, say a poster, at any physical size and the content will adjust and track to that. However, with ARFoundation, for the experience to track and function properly, you must set the physical size of your image marker to be accurate to what you are trying to track/scan.
Neither ARCore nor ARKit support having the same image source multiple times in the same library.
