title: using light in a frame
body: <p><strong>Hello a-Frame Users</strong></p>
  
  <p>I'm trying to play with light in a-Frame in order to create a scene that shows the Lunar (Moon) Phases.</p>
  
  <p>Right now my problem is that I can't combine directional light with ambient light in a way that simulates the Sun, Earth and the Moon.</p>
  
  <p>someone know how can I light the scene in the correct way?</p>
