How to overwrite AvatarIKGoal with TransformStreamHandle in an AnimationJob
I'm trying to script a mirror animation job, but i found that the Muscle value in AnimationStream not include feet, then i do it by the TransformStreamHandle, and it still can't overwrite the foot position and rotation, it seems must to do in "Stream.SetTRS", but it cause more complicated question about root coordinate conversion.
i seen other project done this before, it's possible to mirror AnimationStream runtime like built-in mirror function in StateMachine .

Mirror Clip via AnimationScriptplayable(foot not under control by TransformStreamHandle or Muscle)
