Unreal Control Rig Skill

Control Rig for procedural animation in Unreal Engine.

Overview

This skill provides capabilities for implementing procedural animation using Unreal's Control Rig system.

Capabilities

Rig Development

• Create Control Rig blueprints
• Implement IK solvers
• Configure FK chains
• Handle rig hierarchies

Procedural Animation

• Implement look-at systems
• Create foot IK
• Handle hand IK
• Manage aim offsets

Runtime Modifications

• Modify bones at runtime
• Blend rig outputs
• Handle animation layers
• Manage rig performance

Integration

• Connect with Animation BP
• Handle anim graph nodes
• Integrate with gameplay
• Support retargeting

Prerequisites

• Unreal Engine 5.0+
• Control Rig plugin enabled

Usage Patterns

Foot IK Setup

1. Create Control Rig asset
2. Add foot controls
3. Implement two-bone IK
4. Handle ground detection
5. Apply in Animation BP

Animation Blueprint Integration

Animation Graph:
Linked Anim Layers -> Control Rig Node -> Output Pose

Best Practices

1. Use rig for runtime adjustments
2. Profile rig complexity
3. Test with LOD
4. Handle edge cases
5. Document rig setup
