Core Purpose of Control Rig
Control Rig is Unreal Engine’s built-in rigging and animation control system, used to:
- Create and edit character animations directly within Unreal Engine
1. Rig Structure & Fundamentals
- Understand the hierarchy between bones, controls, and nulls
- Organize a clear and logical rig structure
- Use consistent naming conventions for better control and readability
2. FK / IK Systems
- Use FK (Forward Kinematics) for smooth and natural limb motion
- Use IK (Inverse Kinematics) for grounded and contact-based actions
- Switch properly between FK and IK to maintain animation continuity
3. Constraints & Space Switching
- Apply parent, position, and rotation constraints
- Use space switching between world, local, and object spaces
- Prevent popping, sliding, and unstable motion during animation
4. Baking & Animation Stability
- Bake Control Rig animation into keyframes
- Ensure consistent playback and rendering results
- Avoid physics or simulation issues during final output
