whats the best way to calibrate a tracker 2018? I want the z-axis value to be zero when the tracker is on the floor.
Calibrating with the HMD and SteamVR, where i put both controllers on the floor, is not accurate. Sometimes up to 5-10 cm... (btw. do both Basestations have to be on same height level?)
Calibrating only with the tracker and a Basestation is better, but I have to substract the height of the Basestation... Error is about 2-5 cm...
I am confused, do I always have to fix this manually?
