• Set "combinerType": "Default"to turn off relative orientation tracking with the reference IMU

• Push to driver

With these settings the headset will be tracked by the HMD IMU only. When wearing the headset, if the IMU alignment settings are correct, orientation tracking should feel natural. Please note that without optical system there is no position tracking. If orientation tracking is not working well, the alignment between IMU and the HMD optics (display, lenses) is not good.

Within the range of the optical system, the HMD should now be orientation and position tracked. The tracking will feel a lot less smooth when only using the optical system. However, this mode is a good way to assess the quality of the rigid body adjustment. If orientation tracking completely off, it is better to readjust the rigid body.
