    For example i have this class, and i want to bind element in this data array.
    Code (CSharp):
    1. public class JobDataZone : MonoBehaviour
    2. {
    3.   public float[] data = new float[100];
    4. }
    And this code will throw an error
    Code (CSharp):
    1. animator.BindStreamProperty(animator.transform, typeof(JobDataZone), "data[0]");
