In this game, trackers can be used for your hips, right foot, and left foot.
These roles can be configured from "Manage Vive Trackers" in SteamVR settings.
In SteamVR settings, click "Show Binding Settings UI" to display the settings screen.
Select individual trackers such as "Vive Tracker on Left Foot" and "Vive Tracker on Waist" for your current controller.
Check whether these trackers are set as official bindings.
If you do not have official bindings configured, please do so.
If you don't have any official bindings, click "Create New Binding" to create new bindings.
Now, configure the bindings you've created.
Change any poses set to "Not Configured" to "Pose".
Configure these settings for each of the trackers, and you're finished!
