I’m sorry to hear you’re having trouble using image tracking with Lightship. When you say it wasn’t working, were you receiving an error message? If not, could you please test again with development mode enabled and your device connected to your development computer to read output?
I have same issue, I tried everything to figure out why ARTrackedImagesChangedEventArgs from AR foundation is not running, - no errors, no warninig in Logcat. If I switch to AR core plugin, everything works, please try it out.
I had tried with ARDK 3.0.0, ARDK 3.0.1 and ARDK 3.0.2 with same issue. Changing several parameters in the Android “Other Settings” didn’t work neither.
Building the apk with ARCore works and playing it in Unity with XR Simulation also works.
