Hi @XavierWielemans, I know your post is older, but I just stumbled across it and wanted to reply anyway. Maybe it will help others who are interested. I have also recently needed an offline alternative to anchor sharing. What was sufficient for us was the manual transfer of anchors via the HoloLens device portal. Using the Windows Device Portal #MapManager In our case, it was very important that all HoloLens devices were up to date and that the previous data was reset before importing the data. Otherwise, some anchors were placed incorrectly. I don't know if there is an API for this procedure that can be accessed via a script. But maybe that gives you a clue. Best regards |

Hello, I am trying to set up an off-line demo involving several hololens headsets worn by demo participants in the same physical location. The goal is for everyone to see the same virtual holograms at the same position and orientation in the physical space.
As it has to be offline, disconneted from the internet, Azure Spatial Anchors is not an option, unfortunately.
I have discovered "local anchor transfer" but it is no longer available since Unity 2019 (I am building my demo on top of a Unity 2022 customer project so it has to be Unity 2022).
I have come across XRAnchorTransferBatch (successor of fomer class used for local anchor transfer) but I am struggling to make it work.
Did anyone try that? Or does anyone have some knowledge on how I should proceed?
Any hint or tip would be most appreciated!
Cheers,
Xavier
