APS For Oculus

This is from the legacy tutorial. the tracker data server is no longer needed when using the Quest branch with SteamVR Vive trackers. I you are using APS v8.2.0 you can enable the legacy tracker server input by launching APS and in Steam adding the launch command -use-trackers-server . If you are using any version before APS v8.2.0 then the tracker data server is enabled by default.

Original Tutorial:

If you would like to include full body tracking using SteamVR Vive trackers then please continue reading.

Body trackers are supported in the Oculus branch but require a simple UDP server to stream data from SteamVR into Mocap Fusion.

Enter the IP to your PC or use: 127.0.0.1
Alternatively try the IP: 255.255.255.255

APS OVR-Tracker Data Server

The OVR Tracker server uses the openvr api from SteamVR to stream Vive tracker coordinates data to Mocap Fusion.

You can download the Tracker Data Server from the download button. Be sure that SteamVR is running before starting the server!

Body Tracking

Debugging Window

When launching the server a window appears and prints status for each tracker as it streams data out of the UDP port.

Trackers are valid and report as "TRUE" when SteamVR is active and a VIve tracker has been connected.

Trackers report "FALSE" if there is no device connected or while SteamVR's menu is open. If all trackers show as reporting "FALSE" open the VR view and close the SteamVR menu if it is open.

Note that SteamVR must to be installed for the Vive trackers to function.
You may also wish to enable the SteamVR null-driver to avoid HMD errors.

Trouble Shooting

Note: If you notice SteamVR status reports "Standing By" and trackers are not responding (all False), try closing the APS Tracker Data Server and start the server again.

If that does not work then likely the Steam dashboard might be opened in VR and can't be closed since there is no HMD headset connected to steamVR and no controllers..

Try clicking on "Toggle Dashboard" and the trackers should resume tracking and will be valid/true.
