The sprite material uses the default tk2d/"BlendVertexColor" shader. I also get this error
NullReferenceException: (null)
UnityEditor.SerializedObject..ctor (UnityEngine.Object[] objs)
UnityEditor.Editor.GetSerializedObjectInternal ()
UnityEditor.Editor.get_serializedObject ()
UnityEditor.MaterialEditor.OnEnable ()
However, this hasn't seemed to cause any issues for me and I think that it is a tk2d error. I am targeting the iOS platforms and, if I remember correctly, the error occurs at runtime. It may just not work since I have set up my FSM incorrectly, but I still can't figure out the correct way to get the FSM to work.
Any help on this would be appreciated
Thanks!
