OpenXR body tracking
Support for full body tracking in OpenXR is only just becoming available for a select few platforms. As support solidifies information will be added to this page.
HTC Tracker support
An option that has been available for some time is doing full body tracking using HTC trackers. These are currently supported through SteamVR and on HTC Elite XR headsets. They are exposed through the action map system.
These trackers are identified by their roles which are assigned to them when configured. Simply add XRController3D nodes as children to the XROrigin3D node and assign one of the following trackers:
/user/vive_tracker_htcx/role/handheld_object |
/user/vive_tracker_htcx/role/left_foot |
/user/vive_tracker_htcx/role/right_foot |
/user/vive_tracker_htcx/role/left_shoulder |
/user/vive_tracker_htcx/role/right_shoulder |
/user/vive_tracker_htcx/role/left_elbow |
/user/vive_tracker_htcx/role/right_elbow |
/user/vive_tracker_htcx/role/left_knee |
/user/vive_tracker_htcx/role/right_knee |
/user/vive_tracker_htcx/role/waist |
/user/vive_tracker_htcx/role/chest |
/user/vive_tracker_htcx/role/camera |
/user/vive_tracker_htcx/role/keyboard |
You can now use these as targets for IK modifiers on a full body avatar.
