title: three js mirror fixed mesh reflections
body: <p>After adding a floor mirror the model loses its reflection.</p>
  
  <p>The reflections in the mirror are fine, but they don't show on the model itself and I'm not sure as to why (I'm using the newest three.js:r89).</p>
  
  <pre><code>var groundMirror2 = new THREE.Mirror( 200, 100, {
    clipBias: 0,
    textureWidth: WIDTH * window.devicePixelRatio,
    textureHeight: HEIGHT * window.devicePixelRatio,
    color: 0x777777,
    recursion: 0
  });
  
  groundMirror2.rotation.x = -Math.PI / 2;
  group.add( groundMirror2 );
  </code></pre>
  
  <p>In the second last code line: if the <em>rotation value</em> is positive the model shows up fine.</p>
