title: How to add night sky using Unity 5 procedural skybox?
body: <p>I'm using Unity 5 and it's new procedural skybox. It looks amazing!</p>
  
  <p>In my game, I have a day/night cycle. I can't find a way to use a night skybox which will slowly appear (blend) to replace the procedural skybox when the night comes.</p>
  
  <p>I know a shader exists to blend between two skyboxes, but it won't work with the new procedural skybox.</p>
  
  <p>I want to be able to keep the procedural skybox, so I can keep my amaizing sunrise/sunset, but be able to add stars at night.</p>
