AEL Secondary Motion — Procedural Bone Physics

Bring your characters to life with procedural secondary motion.

AEL Secondary Motion is a production-ready Unity tool designed to add natural, responsive movement to bone chains without the need to author additional animations.

Use it to create convincing secondary motion for hair, tails, ears, clothing, accessories, weapons, creature parts and other articulated elements directly inside Unity.

Fast to set up. Easy to control. Built for production.

AEL Secondary Motion is designed to provide useful results quickly while still giving you the control needed to fine-tune the final behavior.

Whether you're working on a stylized character, a creature, an RPG, an action game or any project with animated bone chains, Secondary Motion helps make movement feel more dynamic and less rigid.

Ideal for:

• Hair and ponytails
• Tails and tentacles
• Ears and character appendages
• Clothing and hanging elements
• Accessories and equipment
• Weapons and props
• Creature parts
• Other hierarchical bone chains

Why AEL Secondary Motion?

• Add secondary motion without creating extra animation clips
• Quickly configure bone chains directly in Unity
• Fine-tune motion to match different characters and objects
• Use visual tools to understand and adjust the simulation
• Designed with both artists and developers in mind
• Built for real production workflows, not just demos

From subtle hair movement to exaggerated creature motion, AEL Secondary Motion gives you a flexible system for adding an extra layer of life to your animations.
