I am writing a small RealityKit app which watches for a specific image, and when the image is seen and then disappears, it starts a video playing (a plane with VideoMaterial). The plane's initial size and location are the same as the image.
This plane moves around as I move the phone, and I want it to stay in place. The most frequent answer I see for this is to set the plane anchor's transform in didUpdate, but didUpdate is not called again after the image disappears. So how/where can I do this?
