Core Capabilities

•  Model Import/Export: Convert PMD/PMX files with automatic bone/vertex group mapping

•  MMD-Specific Rigging: Auto-generate IK constraints, facial morph controllers, and physics-driven bones (skirt/hair dynamics)

•  Animation Support: Load VMD motion/camera files with accurate lip-sync and physics interpolation

•  Material Preservation: Translate MMD shaders to Blender nodes (incl. toon/edge textures)

•  Physics Engine Integration: Real-time simulation for hair/cloth via Blender's physics systems

Key Workflow Advantages

→ Eliminates manual rigging of complex MMD facial systems (eye tracking/blink layers)
→ Solves animation retargeting between MMD skeletons and other rigs
→ Enables high-quality rendering with Cycles/EEVEE while maintaining cel-shaded look
→ Streamlines VTuber model prep for Live2D/3D streaming pipelines

Technical Implementation

• Requirements: Blender 2.83+ (Python 3.7+)

• Installation: Via Preferences > Add-ons > Install (MMD_Tools.py)

• Critical Features:

  • Model Panel: Scale adjustments, rigid body management

  • Bone Mapper: Custom skeleton adaptation

  • Physics Baking: Convert simulations to keyframes

  • Light/Camera Tools: Import MMD scene settings
