Resolution Note:

Root Motion application has changed in 2018.3 to make it more coherent. To reproduce the behaviour of Root curves (Root T and Root Q) with ApplyRootMotion OFF in 2018.3 and following, please turn on Apply Root Motion, and implement OnAnimatorMove like this: public class RootMotion : MonoBehaviour { public bool enableRootMotion; private Animator animator; private void OnAnimatorMove() { if (animator == null) animator = GetComponent<Animator>(); if (enableRootMotion) { animator.ApplyBuiltinRootMotion(); } } }
