title: Hiding vuforia marker
body: <p>I'm making a Unity Vuforia Application and really want to hide marker in real time like this video. (<a href="https://www.youtube.com/watch?v=f5bjhxO4JZQ" rel="nofollow noreferrer">https://www.youtube.com/watch?v=f5bjhxO4JZQ</a>)</p>
  <p>I also already checked an Occlusion Management sample referenced by this link(<a href="https://developer.vuforia.com/forum/unity/hide-real-image-target" rel="nofollow noreferrer">https://developer.vuforia.com/forum/unity/hide-real-image-target</a>) but I couldn't understand it.</p>
  <p>How can I hide or remove the image marker?</p>
