Away3D Forum Loading a model with materials?

I still can’t seem to figure out how to load a model with materials into Away3D 4.0. I’ve got some .3ds and .obj models that I’d like to try, where .3ds is my preferred format.

I’ve looked at the updated 3DS parser, and the new examples, but it’s still not clear to me. The latest ‘soldier ant’ example has the texture embedded in the .swf…

Can it be done? If so, could you help me with some code hints?

Thanks in advance!

Just load the 3DS file using Loader3D, AssetLoader or the AssetLibrary. The dependencies (e.g. textures) will be loaded automatically. If the path is incorrect, an error will be thrown (or an event be dispatched if you are listening for it.)

Hi Richard,

thanks for your reply! But still no joy. This is the code I’m trying to get to work:

loader = new AssetLoader(); 
loader.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
loader.load(new URLRequest('embeds/wagen1.3ds'));

private function onAssetComplete(event:AssetEvent):void
{
    if (event.asset.assetType == AssetType.MESH) {
 var mesh:Mesh = event.asset as Mesh;
   
    } else if (event.asset.assetType == AssetType.MATERIAL) {
 var material:BitmapMaterial = event.asset as BitmapMaterial;
 material.lights = [light];
 material.gloss = 30;
 material.specular = 1;
 material.ambientColor = 0x303040;
    }
} 

...but I can’t figure out how to add the loaded asset to the scene. Sorry for these noob questions

I’d love to see a simple code example that loads a 3ds model and adds it to the scene, maybe it will make the concept click for me.

Thanks in advance!

Have a look at the away3d-examples-fp11 repository on GitHub, where you will find for example this: https://github.com/away3d/away3d-examples-fp11/blob/master/src/Basic_Load3DS.as

hi

to set your material to your mesh, you have to do something like this (code not tested):

loader = new AssetLoader(); 
loader.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
loader.load(new URLRequest('embeds/wagen1.3ds'));

private var mesh:Mesh;

private function onAssetComplete(event:AssetEvent):void
{
    if (event.asset.assetType == AssetType.MESH) {
        mesh = event.asset as Mesh;
        scene.addChild(mesh);
   
    } else if (event.asset.assetType == AssetType.MATERIAL) {
 var material:BitmapMaterial = event.asset as BitmapMaterial;
 material.lights = [light];
 material.gloss = 30;
 material.specular = 1;
 material.ambientColor = 0x303040;
 mesh.material=material;
    }
} 

Signature

sorry…i hope my actionscript is better than my english…

To handle the material by 3DS files as you can utilize the code below. Works well on Away3D 4x. A demo version can be seen in: http://marcosneves.com/extranet/away4Tests/

private function loadModels():void 
{
    Parsers.enableAllBundled();
 
    //Loader model.ac
    acLoader = new Loader3D();
    acLoader.addEventListener(AssetEvent.ASSET_COMPLETE, onMeshLoadComplete);
    acLoader.load( new URLRequest('TREE_AC/TREE_AC.ac') );
   
    //Loader model.3ds
    var maxParser:Max3DSParser = new Max3DSParser();
    maxLoader = new Loader3D();
    maxLoader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onMaxLoaded);
    maxLoader.load( new URLRequest('tree13.3ds'), null, null, maxParser);
   
    this.addEventListener(Event.ENTER_FRAME, onEnterFrame);
}

private function onMaxLoaded(e:LoaderEvent):void 
{
    maxLoader.scale(70); 
 
    var obj:ObjectContainer3D = maxLoader as ObjectContainer3D;
   
    var mesh:Mesh = Mesh(obj.getChildAt(0));
 
    var map:BitmapMaterial = mesh.material as BitmapMaterial;
    map.ambient = 1
    map.specular = 1;
    map.alpha = .7;
    map.lights = [ _light2, _light3 ];//needed lights create
    map.repeat = true;
    map.smooth = true;
    map.bothSides = false;
   
    _view.scene.addChild(maxLoader);
   
}
  
private function onMeshLoadComplete(e:AssetEvent) : void
{
   
    acLoader.removeEventListener(AssetEvent.ASSET_COMPLETE, onMeshLoadComplete);
 
    acLoader.z = 700;
    acLoader.scale(30);

    if (e.asset.assetType == AssetType.MESH)
    {
        mesh = e.asset as Mesh;
  
        var material : BitmapMaterial = mesh.material as BitmapMaterial;
        material.lights = [ _light2, _light3 ];
        material.specular = 2;
        material.alpha = 1;
        material.ambientColor = 0x202030;
        mesh.material = material;
    }
  
    _view.scene.addChild(acLoader);
   

}

you can use assetlibrary to access object mesh like this. Make sure you know your mesh’s name

loader.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
loader.loadData(new mainModel());
container.addChild(loader);

private function onAssetComplete(event:AssetEvent):void
  {
HouseMesh = Mesh(AssetLibrary.getAsset('3DOBJECTNAMEHERE'));
HouseMesh.material =  new BitmapMaterial((new modelTexture()).bitmapData);
}
