I am trying to create a smoking character (Enemy) I have made my model and imported it into unity now what I want to know is how do I add the animated smoke material to the skin of the mesh rater than its centre point. So that it looks like the smoke is in the shape of the mesh. A little like what you see in lost but more defining features. http://www.youtube.com/watch?v=m0X3OKjIlUg
