## Live2D Model Setup
|
|
|
|
Kira currently uses a CSS/SVG animated placeholder avatar. To add a Live2D model:
|
|
|
|
1. Commission or obtain a `.model3.json` (Cubism 4.x format) model
|
|
2. Place the model directory in `frontend/public/live2d/models/`
|
|
3. Rename the model entry point to `kira.model3.json`
|
|
4. The WebGL renderer will auto-detect and switch
|
|
|
|
Required model files:
|
|
- `kira.model3.json` — model definition
|
|
- `kira.moc3` — mesh/deformer data
|
|
- `kira.cdi3.json` — display info (optional)
|
|
- `textures/` — PNG texture files
|
|
- `motions/` — animation files (optional)
|
|
- `expressions/` — face expression files (optional)
|
|
|
|
Recommended creators for custom Live2D models: search VGen, VTube Studio model artists, or Fiverr.
