I have hybrid fbt rift with EV3s. I do not recommend this set up at all as it only works for front facing. It's also very expensive. You need 2 base stations, w steam controller dongles that have been flashed as well as the actual controllers. It still requires the headset's controllers to calibrate and it is always going to be slightly off. It's great for just vrchat and boneworks but do not use it for anything PvP based because it is not reliable.
