Hi, what you’re trying to do is possible, but far harder than you think. I’m going to write another details tech post on how a system can relocalize to a SLAM map (set of 3D points) that it loads from disk/cloud rather than a new map it builds from scratch (as ARKit currently does it). This is needed for multi-player and for permanance of content.

The saving/loading part is a matter of managing & breaking down large maps into smaller maps to a manageable size

The relocalization part is not that hard if the phone orientation etc is exactly as it was (but this is never the case for a real world UX) and very very hard the further away from this original pose that the phone gets.

And both the above challenges are even harder or impossible without access to the algorithms and data structures inside the original SLAM system (ARKit in this case)
