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/)
