Saving/Loading world anchor with WorldAnchorStore and rooms
I am looking at this page to save/load the position of my game objects in a scene.
https://developer.microsoft.com/en-us/windows/holographic/persistence_in_unity
But it does not describe how to handle persistence in different room environments. Is HoloLens (Windows) managing these different rooms automatically? Do developers have to also implement code for handling multiple environments? Can same object have same anchor name in different rooms?
Thanks!

My understanding is that you can load the saved world anchors into your application on start. It does not matter if two or more anchors were placed in different rooms. I believe this is the case, I have not tried it myself.
I don't really follow on the same object having the same anchor name in different rooms. I think It would be two different objects since one object cannot exist in two rooms?

Thank you mtoronto! Yes it makes sense. I guess there will be no situation having single object in two different environment simultaneously. Not sure what happens if user walks from a room to living room that has same object saved. I guess it will be rare situation though

I have a use case for changing rooms:
A trainer uses the hololens in a training program in conference room A. He sets up the elements by placing objects (with Anchors), and runs the training. The anchors work well because each time he fires up the application the objects appear at the WorldAnchors as expected.
The next day, the trainer has been assigned conference room B, which is physically different from A.
Does the Hololens detect that this is no longer the same environment? What happens to the saved anchors in this case ?
At startup the Hololens tries to detect the room we are in. Is this detection somehow automatically linked with Unity WorldAnchors ?
Thanks !
