How can I change a controller's model at runtime without breaking mecanim?

I’ve got a gender select screen and based on this data, in the next scene, the character controller has a model/avatar assigned to it.

During testing I dragged and dropped a model/avatar onto the controller (male or female) and everything worked fine. However, when I assign the model/avatar ‘on the fly’ it doesn’t work. The avatar just floats around.

I’m sure I’m missing something small but I don’t know what it could be. Any help would be appreciated.


	public GameObject MaleModel;
	public Avatar MaleAvatar;
	public GameObject FemaleModel;
	public Avatar FemaleAvatar;

	public GameObject Player;

	GameObject model;
	// Use this for initialization
	void Start () {
		int boy = PlayerPrefs.GetInt ("Gender");

		if (boy != 0) {
			model = Instantiate(MaleModel);
			Player.GetComponent<Animator>().avatar = MaleAvatar;
		} else {
			model = Instantiate(FemaleModel);
			Player.GetComponent<Animator>().avatar = FemaleAvatar;

		model.transform.SetParent (Player.transform);
		model.transform.localPosition = new Vector3 (0, 0, 0);

After a long bit of trial and error, I discovered that the solution to this was to Rebind the Animator after setting the parent and local position.

model.transform.SetParent (Player.transform);
model.transform.localPosition = new Vector3 (0, 0, 0);
