Yes WMR is picky with light sources.
Once figured out though, it ain’t much of a deal anymore.
If you have the gear I really recommend trying to mix WMR with BS. Especially If you have your BS System already fixed, which makes things easier. I’ll roughly estimate one hour of tinkering to make it work.
Do you use openvr space calibrator to do it? I used it for a while but it was kind of finicky with some games and I constantly had to tinker with things to get them in the right positions and calibrated correctly
