Position: Experimental 6DoF tracking support with external SLAM/VIO systems is upstreamed but still being worked on. Tested with RealSense D455 and Samsung Odyssey+, Reverb G2, Oculus Rift S.
Additional Notes: HMD only, no controllers. Tested: HP Reverb, HP Reverb G2, Samsung Odyssey, Lenovo Explorer, others: maybe.
There are some attempts at the Monado project if I’m not mistaken.
Support is unfortunately very limited as of writing
Technically one could use a Vive tracker on top of the headset and use lighthouse tracking, this way it would be easy to use it with Index controllers
Yeah, but that would be a hassle, I liked the fact that most WMR headsets used inside-out tracking
