rigging

面向可变形资产的生产级绑定技能，覆盖骨架设计与命名、IK/FK 选择、约束、权重绘制、机械与面部绑定和驱动器，附人形与机械绑定参考；通过 MCP 在 Blender 中创建骨架、赋予权重并校验，要求在重拓扑后绑定、每顶点不超过 4 个骨骼影响并测试极限姿势。

Rigging

Functional rigs supporting intended motion. Clean deformation. Engine-compatible bone hierarchies.

When to Use

  • Character/creature deformation rigs
  • Mechanical constraint rigs
  • Facial expression rigs
  • Prop rigs (doors, vehicles, weapons)
  • Before any animation work

Workflow

Skeleton Design → Bone Placement → Hierarchy → Constraints/IK
    → Weight Painting → Deformation Test → Export Prep

Armature Naming

Prefix: ARM_[AssetName] Bones: [side]_[region]_[name] — e.g., L_arm_upper, spine_01, jaw

Bone Hierarchy

ARM_Character
├── root
├── spine_01 → spine_02 → spine_03
│   ├── L_clavicle → L_arm_upper → L_arm_lower → L_hand
│   └── R_clavicle → R_arm_upper → R_arm_lower → R_hand
├── L_leg_upper → L_leg_lower → L_foot → L_toe
└── R_leg_upper → R_leg_lower → R_foot → R_toe

IK vs FK

Use IK Use FK
Legs (ground contact) Spine (flexible arc)
Arms (hand placement) Shoulder overlap
Feet planting Finger detail
Mechanical reach Whip/tail motion

Standard: IK legs, FK spine; switchable arms for game characters.

Constraints

Constraint Use
IK Limb positioning
Copy Rotation Mechanical sync
Limit Rotation Joint ranges
Stretch To Tentacles, pistons
Child Of Weapon attach/detach
Shrinkwrap Ground contact (use carefully)

Weight Painting

1. Automatic weights as starting point only
2. Clean weights: normalize per vertex (max 4 influences)
3. Smooth problematic areas (shoulders, hips)
4. Test extreme poses: T-pose, arms up, crouch, jaw open
5. Gradient weights at joints — no hard 1.0/0.0 at bend center

Mechanical Rigs

  • Empty objects as control handles
  • Constraints instead of weight painting
  • Hinge limits match real joint ranges
  • Parent hierarchy mirrors mechanical assembly

Facial Rigs

Approach Use Case
Bone-based Game characters
Shape keys Cinematics, dialog
Hybrid Hero game characters

Minimum game facial: jaw open, blink L/R, brow up/down.

Drivers

  • Gear rotation sync
  • Auto eyelid blink
  • Weapon reload mechanism
  • Procedural antenna/wire motion

MCP Integration

  1. Create armature via MCP
  2. Parent mesh with automatic weights via MCP
  3. Query bone count and hierarchy
  4. Validate weight groups via MCP if supported
  5. Export armature with mesh via export-pipeline

Deformation Test Poses

  • T-pose / A-pose (bind pose)
  • Arms fully raised
  • Deep crouch
  • Neck rotation extremes
  • Jaw wide open (characters)

Constraints

MUST DO

  • Rig after retopology complete
  • Name bones consistently
  • Limit bone influences to 4 per vertex (game engines)
  • Test deformation at extremes before animation
  • Document control scheme for animators

MUST NOT DO

  • Auto weights without cleanup (hero assets)
  • Scale bones in bind pose
  • Rig before topology validated
  • Skip IK pole targets on limbs
  • Mix multiple root bones without documentation
