I'm wondering if anyone has an explanation for this. I'm starting to get into the nuance of AR app production with ARCore, moving past modified tutorials, and trying to build a unity project utilizing AR Core from scratch. I've noticed that the Session.GetTrackables<DetectedPlane>(outPlaneList) always returns planes in a factor of two. At first there's 0, then when you find your first plane, it jumps to 2, then 4, 6, 8, and so on. Is this a bug? The pairs seem to be mostly identical, so I'm not sure why there'd be two for each plane.
