This knowledgebase article will show you how to setup your SteamVR Trackers to track the position and rotation of StretchSense Studio gloves in space. It is intended for users and VTubers who have Valve Base Station 2.0 units and no VR headset who wish to use SteamVR compatible trackers such as HTC Vive or Tundra Trackers for body tracking in software like Warudo.
For this guide we will mostly use Tundra Trackers as these provide a good balance between tracking accuracy, physical footprint and battery life compared with other SteamVR compatible trackers. You can optionally mix other trackers for head tracking, but we recommend using the same tracker type for tracking your hand positions.

Download and install the Steam Desktop client and SteamVR.
Start SteamVR, right-click on your head mounted tracker and click Manage Trackers (see image below).
In the Steam VR settings select Manage Trackers (see below)

SteamVR status window (e.g.

in a text editor.Add
"activateMultipleDrivers" : true
,"forcedDriver": "null"
, to near the top of thesteamvr
section of yoursteamvr.vrsettings
config file and save the file. This is needed to force the NULL driver to be on and use the above tracker in place of a real HMD.

By default, this assumes the tracker is front facing; if you have it mounted to the back of your head you will need to adjust the offsets for the tracker in your animation software, so the character’s head faces the correct direction. |
With SteamVR running, go to the SteamVR status window, open the menu and click Create System Report.
In the Devices tab, find the SteamVR ID of the tracker that matches the one that will be strapped to your head. E.g
/devices/htc/vive_trackerLHR-xxxxxxxx
for HTC VIVE Trackers or/devices/lighthouse/LHR-xxxxxxxx
for Tundra Trackers. Take note of the path and ID as this will be used in subsequent steps.Open
C:\Program Files (x86)\Steam\config\steamvr.vrsettings
in a text editor.Add the new section below to
steamvr.vrsettings
calledTrackingOverrides
, replacingvive_trackerLHR-xxxxxxxx
with the serial number and name of the Tundra tracker you are using for your head, found in step. This will force the head mounted tracker to be used as the HMD tracking point.Code Block "TrackingOverrides" : { "/devices/lighthouse/LHR-xxxxxxxx" : "/user/head" }
