title: Unity Frustum culling Issue
body: <p>I'm creating a game that utilizes off center projection. I've got my game set up in a CAVE being rendered in a cluster, over 8 PC's with 4 of these PC's being used for each eye (this creates a stereoscopic effect). To help with alignment in the CAVE I've implemented an off center projection class.</p>
  
  <p>This class simply tells the camera what its top left, bottom left &amp; bottom right corners are. From here, it creates a new projection matrix showing the the player the left and right of their world. However, inside Unity's editor, the camera is still facing forwards and, as a result the culling inside Unity isn't rendering half of the image that appears on the left and right screens.</p>
  
  <p>Does anyone know of a way to to either turn off the culling in Unity, or find a way to fix the projection matrix issue?</p>
