Facetracker with VTube Studio
Facetracker can be used with VTubeStudio. The setup for this is rather simple.
Inside Steam right-click VTube Studio and chose Properties
Navigate to Installed Files and click on Browse....
This will open up your file browser at the install location of VTube Studio.
In here navigate to VTube Studio_Data/StreamingAssest/ and create a new file called ip.txt.
Open that file and enter:
ip=0.0.0.0
port=11573
Make sure port matches Facetracker's port.
Note: If you set ip to any IP-Adress of any other device in your local network running Facetracker you can receive tracking data from that device.
After restarting VTube Studio and running Facetracker the tracking data should get picked up right away.
