Troubleshooting
The render quality is low, or I see white lines/pixels. How can I fix it?
This is usually caused by anisotropic filtering settings. See:
The model cannot open its mouth in VTube Studio.
In VTube Studio, go to General Settings > External Connections and set Lipsync Type to Advanced Lipsync. You don't need a microphone to use this feature, just change the setting is enough.
If the issue continues, check whether VoiceSilence is bound correctly to the VTS input parameter with the same name. When the mic is off, this parameter should be 1 for mouth tracking to work properly.
