# 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 ## References - [Control Rig Documentation](https://docs.unrealengine.com/5.0/en-US/control-rig-in-unreal-engine/)
