Dear Vincent & Tony!
I'm stuck at the same place.
Have a currently working multi user Hololens 2 app (what only send some positions from server to client) not a whole "netcode"-like thing.
Want to migrate my app to HTC XR Elite, almost all the functions working now with OpenXR.
I successfully achieved the passthrough layer and etc, now only a position tracking is the problem.
Do you have any source of information what could help me achieve ARUCO markers tracking with OpenXR?
I only found the base Wave.Native.WVR_Android implementation of ARUCO tracker and obviusly because my project uses OpenXR it throws an exception.
Thanks,
Best regards,
Balint Szendeffy
