Virmii generates a 3D VTuber avatar from a single character image, then brings it to life: AI-generated expression sets, face tracking in the browser, and a Live Studio that plugs into OBS as a Browser Source. Models can also be downloaded as VRM files.
The maker is upfront that AI generation may change a character's face, clothing and proportions, so an exact match is not guaranteed - each model version includes up to two free retries for missing or failed images. You can try real avatars without signing up, and expression sets start from 20 credits.
