title: Box2D Light to ignore all bodies
body: <p>I have type of light in my game that needs to penetrate all obstacles, how can I achieve this?</p>
  
  <p>I tried this: </p>
  
  <pre><code>final short IGNORED = 0x001;
  
  FixtureDef fd = new FixtureDef();
  fd.filter.categoryBits = IGNORED;
  fd.filter.groupIndex = IGNORED;
  fd.filter.maskBits = IGNORED;
  
  new PointLight(rayHandler, 1000, Color.CYAN, 1000, 200, 400);
  
  PointLight.setContactFilter(IGNORED,IGNORED,IGNORED);
  </code></pre>
  
  <p>but I still get shadows from that light.</p>
  
  <p>Another thing is that my shadows are black and continue forever, is there a way to create shadows that arent so dark and long?</p>
  
  <p>Basically this is what I get:

  <p>but this is what I want:
