[Urgent] Animator replay the same animation when root motion applied.

Hi guys,

I have an Animator component attached to a gameObject, and with the applyRootMotion checked. And the simple thing I want to do is replay the animation used by that animator from the same starting position.

Code (CSharp):

1.         model.transform.ResetTransformLocal();
2.         model.animator.rootPosition = model.transform.position;
3.         model.animator.rootRotation = model.transform.rotation;
4.         model.animator.Play("someAnimation", -1, 0.0f);

So I reset the gameObject's transform to default, and then apply its world position to the rootPosition of the animator. But strange things happen sometime: the animation is not guaranteed to be played at the same path each time, which means, the model might be going in the wrong direction next time I replay the animation.
