- Two-phase construction: Building + Interior Lighting
- Configurable performance settings

### Interior Lighting (Unique!)

- Smart enclosed-air detection
- Fully configurable spacing and search radius

### Easy to Use
1. Craft the Voxel Builder Controller
2. Right-click to open GUI
3. Select your STL file
4. Preview with real-time rotation
5. Place anchor and watch it build!

### Server-Safe
- Distance limits and dimension locks
- Per-player and global build limits
