title: how can I set the size of a directional light in Three.JS?
body: <p>I've added a directional light to my scene, but it doesn't show all the shadow. The shadow gets cut off, just like when the FOV of a spotlight is too small.</p>
  
  <p>When I enable the shadowCameraVisible, i see that my light is like a big box which shows the shadow (which makes sense). The question is: how can I make this 'box' bigger?</p>
