title: Three js black color of material to transparent
body: <p>How to make Lambert material from texture with transparent black color without alphaMap.</p>
  
  <p>I have sphere with clouds texture. I need to be black color transparent, if i use blending, it have affect on shadow, i need keep behavior like MeshPhong material, but only with transparent black color.</p>
  
  <pre><code>var cloudsMaterial = new THREE.MeshLambertMaterial( { 
                          color: 0xffffff, 
                          map: THREE.ImageUtils.loadTexture( "img/planets/clouds.jpg" ),
  
                          specular   : new THREE.Color("rgb(255,255,255)"),
                          shininess  : 0.1,                              
                          depthTest  : 0,
                          blending   : 1,
                          transparent: true,
                          bumpScale  : 1, //0.8
                          bumpMap    : THREE.ImageUtils.loadTexture( "img/planets/bump.jpg" ),                                                      
                          } );
  </code></pre>
  
  <p>what is the correct way, to setup blending, or another attributes?</p>
