Why can’t I see the model hands in Hi5 VR Glove Calibration Sample scene?

Please check that:

• The dongle is plugged in. (You can unplug the dongle and then re-plug it back in).
• The glove is turned on. (There is a button on the side of the battery housing).
• The glove and the dongle are paired and well connected (both the lights on the glove and dongle should be flashing).
• VIVE trackers or other tracking devices are turned on and are mounted on the gloves properly.
• The SteamVR program is functioning well.
• You have successfully calibrated all the sensors as shown in the calibration tutorial.
• All of the HTC VIVE devices are set up properly.
• The SteamVR program is functioning well and it shows that the tracking devices are connected.
• The tracking devices are turned on.
