title: Unity light creates rare blue light on sky
body: <p>I'm doing a Unity project where I basically have a Directional Light rotating around the map, starting on 0 to 360 degrees.</p>
  <p>However, when it gets dark = rotation from 100 to 120 degrees I get this strange blue light coming from the sky, does anybody have any idea on how to avoid this blue thing appearing?</p>
