title: Away3D (4.x Broomstick) - How do I set the alpha of a material loaded with a 3DS file?
body: <p>I have loaded a model using the 3DS parser that is already linked to a material and loads fine. I would like to make this model semi-transparent part of the time but not all of the time. I would like to just set alpha = .5 but when I target the materal that is not an option.</p>
  
  <p>Here is the code and using:</p>
  
  <pre><code>        var slingPar:Max3DSParser = new Max3DSParser();
          var slingLoader:Loader3D = new Loader3D();
          sling = new ObjectContainer3D();
          slingLoader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, function(e:LoaderEvent):void
          {
              var mesh:Mesh = Mesh(sling.getChildAt(0));
              mesh.material.lights = [light1, light2, light3];
              mesh.rotationY = 180;
  
          });
          slingLoader.load(new URLRequest("assets/game/slingCup.3DS"),slingPar);
          sling = slingLoader;
  </code></pre>
  
  <p>I tried</p>
  
  <pre><code>mesh.material.alpha = .5
  </code></pre>
  
  <p>But had no luck. Any Ideas?</p>
