How do I adjust the angel the lights comes from the sky...
  
 
  
  
    go into the entity properties (the 'n' button on the keyboard) and do a key, angle with a value of whatever you want the lights angle to be.
 
 that is if you are working with a spot light like light, including the sun I would think.
  
 
  
  
    Target the light at an info_null.
