Root Motion

Root Motion is a special feature of the Flax animation system that can be used to extract the motion from the animated model root node and apply it to the actor. This is useful, for example, to create animation-driven characters. Flax supports extracting root motion from the custom node and motion blending so it's possible to achieve realistic looking results.

Tips

You can manually specify the root node for the motion extracting when importing the animation. Use Root Node Name field (more info here).

If your character uses Character Controller or kinematic rigidbody you may want to apply the root motion to it instead of to animated model. To do this simply assign the target object to AnimatedModel.RootMotionTarget.
