rift lighthouse hybrid has problems because rift cameras are infared detectors and the controllers emit infared signals for tracking and the lighthouse base stations emit infared light that the trackers detect. the lighthouses occasionally blind and confuse the oculus tracking cameras and the oculus controllers that emit infared pulses occasionally confuse vive trackers when they get close (happens most frequently with the hip tracker puck). wmr doesnt have this issue because it doesn't use infared tracking at all.
