@eragon There's multiple approaches to VTubing, you can go 3D, animated 2D, or static 2D.
For 3D you get someone to make a 3D model for you and use software called VSeeFace.
For 2D you pay an artist to draw model art which then is rigged in either Live2D or Inochi Creator, and software like VTube Studio or Inochi Session allows for face tracking to control the model.
For static 2D you commission various frames and software exists to animate those based on microphone input.
