title: Zigfu + unity3d OSX
body: <p>Has anyone managed to upgrade the Unity package from Zigfu to work with current version of unity?
  I've used the particle updaters etc.
  But sample scenes show warnings like this:</p>
  
  <p><code>The referenced script on this Behaviour (Game Object 'ZigFu') is missing!
  </code></p>
  
  <p>No idea how to update the scripts. I'm not getting any other errors just warnings.</p>
