All new animation
With Mecanim, our new animation system, you can animate any character or object with astonishing ease. Animate even vast armies with retargeting and Unity’s stability and power, combined with new optimizations, such as skinned mesh instancing, ensure smooth runtime performance. Easily construct and edit complex state machines and blend trees for complete control of how your characters move.
For true professional polish, use Pro-only IK rigs to fine-tune each detail in your animations: perfectly position legs throughout a jump sequence, or make hands grip a ledge, wrap around a doorknob or pick up objects exactly how you want them to. More about Mecanim
