SteamLink Module for VRCFT

The Implementation is EXPERIMENTAL and may change without notice causing app to fail.

Install

• Download Latest Release from Releases
• In VRCFT go to modules and install from zip

Setup

• DO NOT CHANGE VRCFT NETWORK SETTINGS

• In VR you will need to change a few settings in SteamLink, you will need to have "Advanced Settings" to show

  • Enable OSC - on
  • Share eye tracking data... - on
  • Share Face tracking data... - on
  • OSC Output Port - 9015 (Custom: VRCFT,Etc.)

Mixed Tracking / 混合追踪

This module automatically cooperates with other VRCFT tracking modules to avoid overlapping data:

• When another module's face tracking is already active (initialized first), this module only claims eye tracking. VRCFT's main page will show "Eye Tracking Active" without "Expression Tracking Active", and this module will stop writing expression data.
• When another module's eye tracking is already active, this module only claims expression tracking (and vice versa).
• The claim is decided by the handshake with VRCFT during module initialization. Module load order (by module folder name) determines which module claims first.

Manual override (tracking_config.json)

Because load order is alphabetical by module folder (effectively random), this module may load before another face tracking module and claim everything. In that case, create/edit the config file next to the module DLL:

%APPDATA%\VRCFaceTracking\CustomLibs\2a8c8080-2a76-46af-bf76-1da7c0127ef8\tracking_config.json

{
  "EyeTracking": "Auto",
  "FaceTracking": "Off"
}

Values (case-insensitive):

Value	Behavior
Auto	Follow VRCFT handshake: claim only what no other module has claimed (default)
On	Always claim this tracking type
Off	Never claim this tracking type (let other modules take it)

Example: with another face tracking module installed, set FaceTracking to Off so SteamLink only provides eye tracking. Restart VRCFT after changing the config.

The config file is created automatically with defaults on first launch.

Note: toggling this module off on VRCFT's main page pauses its data output until toggled back on.
