  • Configure Root motion as usual from motion configuration section of animator importer window:

    Root Motion Config

  • Generic rigs only: Configure Root node field in model importer window to the bone that will be used to drive object movement.

  • Enable the Apply Root Motion checkbox in the Unity Animator component:

Custom root motion handling​

Sometimes root motion calculated movement needs to be propagated to other systems. There is the RootMotionVelocityComponent that can be used to obtain root motion velocity for the current frame. If you don't want to move the animated entity by Rukhanka's root motion code, it can be disabled in RigDefinitionAuthoring. Root Motion Mode property controls Rukhanka's root motion operation mode:

  • Normal. Standard operation mode. In this mode Rukhanka will move entity according to root motion tracks if this is requested.
  • Disable Builtin Movement. Calculate root motion, but do not apply it to the entity position.

In both modes RootMotionVelocityComponent gets updated with current frame velocity values.
