How Mesh Avatar Studio Was Released: Creating Live2D-Style Avatars from a Single Image
The developer of AITuber OnAir published Mesh Avatar Studio on GitHub, a tool for creating Live2D-style avatars from a single illustration. The article traces the process from an Opus 5.5 experiment to editor-based mesh correction, blinking, lip sync, head movement, breathing, and hair motion. It also explains how generated eye and mouth variants were combined with mesh deformation, making it a practical reference for improving AITuber avatar expression quality.

The practical part is the comparison between mesh-only motion and generated expression variants. I am watching how this lowers the barrier to richer AITuber faces.
