Tracked images not removed even after assigning fresh mutable reference image library [Bug]

[badrdouah]

I set up ARKit to track Image A by creating a Mutable Reference Image Library (MRL). Later, I create a completely new MRL instance with Image B to track instead. However, ARKit still tracks Image A, even though it shouldn’t be part of the new library.

You can clearly see this issue by checking the child GameObjects under XROrigin → Trackables, where the previously tracked image (Image A) remains.

Additionally, I’m facing another problem: the name property of the tracked image is always empty (""). Even though I assign a name when creating the Mutable Reference Library, the trackedImage.referenceImage.name always returns an empty string.

library = aRTrackedImageManager.CreateRuntimeLibrary() as MutableRuntimeReferenceImageLibrary; if (library == null) { Debug.LogError("Failed to create runtime library"); yield break; } addReferenceImageJobState = library.ScheduleAddImageWithValidationJob( generatedQRCodeTexture, "test", 0.09f );
