VTuber Applications

Corvus Connection drives VTuber and stream-toy apps that run on your PC. VTube Studio is the first, with more (TITS, THICC, and VeeSeeFace) planned. Control your avatar from visual flows, chat commands, and scripts, and react to avatar events, all as native building blocks.

Set up VTube Studio

In VTube Studio, open Settings and enable the API (default port 8001).
In Corvus Connection, open Settings, then VTube Studio, and turn the integration on. The host and port are pre-filled.
The first connection asks for approval: click Allow inside VTube Studio. The status reads Connected once it is authorized.

VTube Studio integration is an alpha preview; enroll in the Portent ring to enable it.

Nodes

The Nodes reference lists the full VTuber category. Highlights:

Actions: Trigger Hotkey, Set Parameter, Activate Expression, Load Item, Unload Item, Move Item, Control Item Animation, Load Model, Color Tint, and Move Model. Load Item emits the new item instance id, so a later Move or Unload can target that exact instance.
Reads: Get Current Model, List Available Models, List Hotkeys, List Expressions, List Input Parameters, Get Parameter Value, List Live2D Parameters, List Items, and Get Scene Color Overlay. Each returns an empty result when VTube Studio is closed, so the flow keeps running.
Triggers: On Model Loaded, On Hotkey Triggered, On Model Clicked, On Tracking Found, On Tracking Lost, On Model Moved (throttled), and On Animation Event.

Chat command and token

Chat: !hotkey <name> triggers a hotkey and !expression <name> activates an expression (moderators and the broadcaster by default). See Commands.
Template tokens: {vts.currentModel} renders the loaded model name, {vts.currentExpressions} the active expression names, and {vts.faceFound} the tracking state.

Sample flow

Wave on click: an On Model Clicked trigger into a VTuber: Trigger Hotkey action fires your wave animation whenever a viewer clicks your avatar. Browse the Examples catalog for this and other ready-made flows.
