When working with Away3D youll eventually need to load a complex model. The code for loading a 3D model into Away3D is fairly easy. It is almost as simple as loading a plane, cube, or cone. this code is about loading a 3d stadium.

1.Load your Model

var loader3D:Loader3D = new Loader3D();
loader3D.load(new URLRequest("assets/stadium.md5mesh"));            
loader3D.addEventListener(AssetEvent.ASSET_COMPLETE, onLoadComplete);

2.Handle the load success

And here goes the full code

import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.Loader;
import flash.display.LoaderInfo;
import flash.events.Event;
import flash.net.URLRequest;
import com.track.event.ModelEvent;

public class ModelHandler
{
    private var _mesh:Mesh;
    public function ModelHandler()
    {
                super();
        }
    public function loadModel(name:String, path:String=""):void// called from manager
    {
        trace("loading model");
        Loader3D.enableParser(MD5MeshParser);
        var loader3D:Loader3D = new Loader3D();
        loader3D.addEventListener(AssetEvent.ASSET_COMPLETE, onLoadComplete);
        loader3D.load(new URLRequest("assets/stadium.md5mesh"));
    }


    private function onLoadComplete(evt:AssetEvent):void
    {
        if (evt.asset.assetType == AssetType.MESH) 
        {
            trace("loaded model");
            _mesh = evt.asset as Mesh;

            loadMaterial();
        }
    }

    private function loadMaterial():void
    {
        trace("loading material");
        var loader:Loader = new Loader();
        loader.contentLoaderInfo.addEventListener(Event.COMPLETE, materialLoaded);
        loader.load(new URLRequest("assets/Stadium_Diff.jpg"));
    }

    private function materialLoaded(evt:Event):void
    {
        trace("loaded material");
        var bitmapData:BitmapData = Bitmap(LoaderInfo(evt.target).content).bitmapData;
        _mesh.material = new TextureMaterial(new BitmapTexture(bitmapData));


    }
}

}
