Hi, I'm building a Unity ARKit mobile app these days: there are several 3D models in prefabs showing up in 21 rooms/places of a museum, so I had to use image tracking to have one model per place.Although most of the app works, some models don't show up.I have a few questions/topics:- it seems the tracking is affected by the number of reference images to be tracked- lighting is important, so I had to use day and night reference images.- in the Unity ARkit package, there is a "MaxImages" parameter, is it relevant and if I put 20, it would stop tracking the images in the reference database after index 20?- are there other parameters I can tweak to help tracking? it seems I don't have much control on other parameters, if any.Thank you for any hint!
