Have some troubles with image tracking in unity. When i try to use more than one marker, i see:
"NullReferenceException: Object reference not set to an instance of an object
easyar.ImageTracker.unloadTarget (easyar.Target target, easyar.CallbackScheduler callbackScheduler, System.Action`2 callback) (at Assets/EasyAR/Scripts/csapi.cs:4687)".
But when i use any only one of my three markers, everything works fine. Solution?
I think that markers destroys, before they added to traklist. But I don't know why.
