title: Unity 3D fade from one skybox to another
body: <p>I have four different skyboxes, one for each season in my game. </p>
  
  <p>How can I create a fade transition between the skyboxes in c#?</p>
  
  <p>So for example, at a certain point, the summer skybox fades into the autumn skybox.</p>
  
  <p>Thank you!</p>
