Rigging

Skeleton and Joint Hierarchy

Joint Placement

Anatomical Accuracy: Place joints following anatomical structure
Deformation Considerations: Position joints for optimal deformation
Joint Orientation: Orient joints for proper rotation axes
Joint Hierarchy: Create logical parent-child relationships
Naming Conventions: Use consistent, descriptive joint names
Scale and Proportions: Maintain proper scale and proportions

Joint Types

Ball Joints: 3 degrees of freedom (shoulder, hip)
Hinge Joints: 1 degree of freedom (elbow, knee)
Universal Joints: 2 degrees of freedom (wrist, ankle)
Root Joint: Base of the skeleton hierarchy
End Joints: End of joint chains (fingertips, toes)

Joint Hierarchy

Root: Top of the hierarchy (hips, pelvis)
Spine: Spine joints from pelvis to neck
Limbs: Arms and legs with shoulder/elbow/hand and hip/knee/foot
Head: Head and facial joints
Fingers: Finger joints for detailed hand animation
Toes: Toe joints for detailed foot animation

IK and FK Controls

Inverse Kinematics (IK)

IK Solvers: Calculate joint positions from end effector
IK Handles: Controls for IK chains
Pole Vectors: Control IK chain orientation
IK/FK Blending: Switch between IK and FK
IK Constraints: Limit IK movement
IK Applications: Legs, arms, spine, fingers

Forward Kinematics (FK)

FK Controls: Rotate joints directly
FK Chains: Parent-child joint relationships
FK Applications: Spine, fingers, toes, tail
FK Advantages: Intuitive, predictable, easy to animate
FK Disadvantages: Time-consuming for complex poses

IK/FK Switching

Blend Controls: Switch between IK and FK
Match IK to FK: Match IK pose to FK pose
Match FK to IK: Match FK pose to IK pose
Seamless Transitions: Smooth switching between modes
Animation Considerations: Plan IK/FK usage in animation

Facial Rigging and Blendshapes

Blendshapes

Shape Keys: Create facial expressions
Expression Targets: Create expression targets for blendshapes
Phonemes: Create phoneme targets for lip sync
Eye Shapes: Create eye shape targets
Brow Shapes: Create brow expression targets
Mouth Shapes: Create mouth expression targets

Facial Rigging Techniques

Joint-Based: Use joints for facial animation
Blendshape-Based: Use blendshapes for facial animation
Hybrid: Combine joints and blendshapes
Morph Targets: Alternative to blendshapes
Bone-Driven: Use bones to drive blendshapes

Eye Rigging

Eye Joints: Create joints for eye movement
Eye Controls: Create controls for eye direction
Eyelid Rigging: Create controls for eyelid movement
Pupil Rigging: Create controls for pupil dilation
Eye Constraints: Limit eye movement to natural range

Constraint Systems

Constraint Types

Parent Constraint: Constrain object to follow parent
Orient Constraint: Constrain object orientation to target
Point Constraint: Constrain object position to target
Aim Constraint: Constrain object to aim at target
Scale Constraint: Constrain object scale to target
Geometry Constraint: Constrain object to follow geometry

Constraint Applications

IK Controls: Use constraints for IK controls
FK Controls: Use constraints for FK controls
Space Switching: Switch between different spaces
Follow Through: Use constraints for follow-through animation
Secondary Motion: Use constraints for secondary motion

Constraint Best Practices

Constraint Order: Order constraints for predictable results
Constraint Weighting: Use constraint weights for blending
Constraint Limits: Limit constraint influence
Constraint Performance: Optimize constraints for performance
Constraint Cleanup: Remove unnecessary constraints

Weight Painting Techniques

Weight Painting Basics

Vertex Groups: Assign vertices to bone groups
Weight Values: Assign weight values (0-1) to vertices
Weight Influence: Control bone influence on vertices
Weight Normalization: Normalize weights for predictable results
Weight Smoothing: Smooth weights for natural deformation
Weight Mirroring: Mirror weights across symmetry

Weight Painting Tools

Weight Brush: Paint weights directly on mesh
Smooth Brush: Smooth weights for natural deformation
Blur Brush: Blur weights for smooth transitions
Add Brush: Add weight to vertices
Subtract Brush: Subtract weight from vertices
Normalize: Normalize weights for predictable results

Weight Painting Best Practices

Joint Areas: Concentrate weight around joints
Deformation Paths: Follow natural deformation paths
Weight Distribution: Distribute weight evenly
Weight Limits: Limit weight to appropriate areas
Weight Testing: Test weights with animation

Rig Optimization for Real-Time

Optimization Techniques

Reduce Bone Count: Remove unnecessary bones
Simplify Constraints: Simplify constraint systems
Optimize Weights: Optimize weight painting
Use IK/FK Efficiently: Don't overuse IK
Reduce Control Count: Reduce control complexity
Optimize Hierarchy: Optimize joint hierarchy

Real-Time Considerations

Frame Rate: Maintain target frame rate
Memory Usage: Minimize rig memory
CPU Usage: Reduce rig CPU cost
GPU Usage: Minimize rig GPU impact
Network: Reduce network bandwidth for multiplayer

Platform-Specific Optimization

Mobile: Lower bone count, simpler rigs
Console: Medium optimization, balance quality and performance
PC: Higher quality, more complex rigs
VR: High frame rate priority, reduced complexity
AR: Real-time performance priority

Rig Export and Integration

Export Formats

FBX: Most common format, supports rigging
Maya ASCII/Binary: Maya native format
Blender: Blender native format
Collada (DAE): Open standard format
glTF/GLB: Web-ready format

Export Settings

Bake Animation: Bake all constraints and IK to FK
Include Skeleton: Include skeleton in export
Include Blendshapes: Include blendshapes in export
Root Motion: Include or exclude root motion
Animation Takes: Export specific animation takes

Integration

Unreal: Import FBX, configure Skeleton, set up Animation Blueprint
Godot: Import glTF/FBX, configure Skeleton, set up AnimationPlayer
Web: Use Three.js or Babylon.js with glTF rigging
Custom: Parse rig data and apply to custom systems

cache-components

Expert guidance for Next.js Cache Components and Partial Prerendering (PPR). **PROACTIVE ACTIVATION**: Use this skill automatically when working in Next.js projects that have `cacheComponents: true` in their next.config.ts/next.config.js. When this config is detected, proactively apply Cache Components patterns and best practices to all React Server Component implementations. **DETECTION**: At the start of a session in a Next.js project, check for `cacheComponents: true` in next.config. If enabled, this skill's patterns should guide all component authoring, data fetching, and caching decisions. **USE CASES**: Implementing 'use cache' directive, configuring cache lifetimes with cacheLife(), tagging cached data with cacheTag(), invalidating caches with updateTag()/revalidateTag(), optimizing static vs dynamic content boundaries, debugging cache issues, and reviewing Cache Component implementations.
