title: UI Elements not affected by light
body: <p>I'm trying to make a menu screen in which all the UI elements (buttons, text...) are completely dark and by touching the screen you create a fire (or just an area light) that makes the UI elements visible.</p>
  
  <p>Sort of like <a href="http://cdn.akamai.steamstatic.com/steam/apps/221260/header.jpg?t=1447356660" rel="nofollow noreferrer" title="this">this</a></p>
  
  <p>I read that the default shader for the UI elements isn't affected by light, but i can't seem to change it.</p>
  
  <p>How do I go about doing this?</p>
