I tried to load an animator controller from asset bundle, this works in Unity editor. But I only gets null on “rac” when running on iPhone.
RuntimeAnimatorController rac = animationBundle.LoadAsset<RuntimeAnimatorController> ("cha_ac_0");//original ac name
if (rac == null)
Debug.Log ("RACNULL");
AnimatorOverrideController myOverrideController = new AnimatorOverrideController (rac);
animator.runtimeAnimatorController = myOverrideController;
