title: Combine THREE.MeshFaceMaterial and THREE.BackSide?
body: <p>Using three.js v56:</p>
  
  <p>I have an array of textures called <code>materialArray</code>, then I create</p>
  
  <pre><code>var cubeMaterial = new THREE.MeshFaceMaterial( materialArray );
  </code></pre>
  
  <p>However, I would like this texture to be reversed; for a "normal" material called <code>simpleMaterial</code>, one would enter:</p>
  
  <pre><code>simpleMaterial.side = THREE.BackSide;
  </code></pre>
  
  <p>Alas, this has no effect in this case; the material is still displayed on the "front" side.
  So, how can the texture be set to the backside when working with an array of textures as in MeshFaceMaterial?</p>
  
  <p>Thanks in advance!</p>
