KAOREN – Real-time collaborative 3D face sketching with VRM models

Summary: KAOREN is a browser-based app for practicing face sketches using VRM 3D heads with real-time collaboration. It syncs camera views, layers, and strokes via WebSocket without uploads or signup, enabling shared drawing sessions and timed croquis rounds.

What it does

Users can load built-in or local VRM models, run timed sketch rounds with randomized angles and expressions, and collaborate in shared rooms where all participants see the same 3D view and draw on shared layers. The app exports combined 3D views and sketches as PNG files.

Who it's for

Artists and educators seeking interactive face sketch practice and live drawing feedback in real time.

Why it matters

It overcomes static reference limitations and enables synchronized process feedback during collaborative drawing sessions.
