MakeMeVtuber

Transform your Minecraft player into a VTuber-style avatar with a single command.

What does it do?

MakeMeVtuber opens a separate render window that displays your player model on a chromakey background — ready for OBS or any streaming software. The camera follows your head, the mouth moves with your microphone, and everything is customizable.

Features

VTuber avatar window — renders your player model in a separate window with green/blue/transparent background
Microphone lip-sync — mouth opens in real-time based on your mic volume
Spring camera — smooth camera that follows your head rotation
Chromakey backgrounds — green, blue, or transparent (experimental)
Customizable mouth — adjust position, size, threshold, gain, and intensity
Dither fade — body parts dissolve when looking down to keep focus on the face
Lightweight — runs on a separate thread, minimal FPS impact
