title: A-Frame Why mesh disappears at certain camera angle?
body: <p>I am playing around with this A-Frame example on geometry instancing: <a href="https://cdn.rawgit.com/takahirox/aframe-instancing/153e6d9b128b807ebe606b1c65a3f43c09f7af61/index.html" rel="nofollow noreferrer">https://cdn.rawgit.com/takahirox/aframe-instancing/153e6d9b128b807ebe606b1c65a3f43c09f7af61/index.html</a>.</p>
  
  <p>The issue is that when I put my Oculus rift headset and move my head around (90 degrees to the left or right), the mesh would disappear suddenly from the screen and VR headset.</p>
  
  <p>Is there a way to prevent the mesh from disappearing.</p>
  
  <p>Thank you!</p>
