Question Use playable set human root poisition

Hi, I try to use AnimatorControllerPlayable set human animator(Apply Root Motion is true) root position, but it dose't work.
This is my code, is possible?

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Animations;
3.  
4. public struct KeepFoot : IAnimationJob
5. {
6.     public TransformStreamHandle foot;
7.     public TransformStreamHandle root;
8.  
9.     private Vector3 footPos;
10.     public void ProcessAnimation(AnimationStream stream)
11.     {
12.         stream.velocity = Vector3.zero;
13.         var buf = stream.AsHuman();
14.         buf.bodyLocalPosition = Vector3.zero;
15.         buf.bodyRotation = Quaternion.identity;
16.         root.SetRotation(stream, Quaternion.identity);
17.  
18.     }
19.  
20.     public void ProcessRootMotion(AnimationStream stream)
21.     {
22.         stream.velocity = Vector3.zero;
23.         var buf = stream.AsHuman();
24.         buf.bodyLocalPosition = Vector3.zero;
25.         buf.bodyRotation = Quaternion.identity;
26.         root.SetRotation(stream, Quaternion.identity);
27.     }
28. }
