This sounds insane, but I'm unable to detect the right leg with the vision framework. import Vision let rightLeg = try observation.recognizedPoints(.rightLeg)       print(rightLeg) The result is: [C.VNHumanBodyPoseObservationJointName(_rawValue: left_foot_joint): [0.000000; 1.000000], C.VNHumanBodyPoseObservationJointName(_rawValue: left_leg_joint): [0.751968; 0.281050], __C.VNHumanBodyPoseObservationJointName(_rawValue: left_upLeg_joint): [0.767090; 0.715324]] As you can see, it seems to be tracking the left leg. This is similar to the result if I change the groupName value to .leftLeg. .leftArm & .rightArm work as expected as well. Only .rightLeg is not working. I've tested detection on several people with the same results. How is this possible?
