Hi All, I am trying to figure out a simple thing to do using ARkit and Unity and I need help with it. I would like to place 3D objects in my room on detected planes and save the 3D objects position and rotation along with the detected feature points on to a file. Then I want to be able to load the saved session again by opening the app and see the 3D objects right where I kept them in AR. Now I have been able to save and load the world map using ARkit plugin in unity and I have managed to place objects where I want to place them using a Tap on screen. But I am not able figure out how to save the position and orientation of the 3D objects placed in my room and load them along with the world map. I tried saving the world position of the 3D objects and reload them after loading world map, but it is highly inaccurate. The key part is I want the load the 3D objects at the whatever places I kept them before saving the world map. I keep reading about AR Anchors or World Anchors in blogs but I don't see it with a specific implementation in unity. Could anybody please guide me on how to efficiently and accurately save the position and rotation of the 3D objects in a session so that they could be loaded back later at the same place? I am building this app with unity 2019.2.0 and ARkit XR plugin 2.1.1. Look forward to suggestions and advises. Regards, Sanket.
