Hi,

I understand how to load a 3d object (.OBJ) with a single texture.

private function initMaterials():void
  {
   //setup custom bitmap material
   headMaterial = new TextureMaterial(new BitmapTexture(new Diffuse().bitmapData));
   headMaterial.normalMap = new BitmapTexture(new Normal().bitmapData);
   headMaterial.specularMap = new BitmapTexture(new Specular().bitmapData);
   headMaterial.lightPicker = lightPicker;
   headMaterial.gloss = 10;
   headMaterial.specular = 3;
   headMaterial.ambientColor = 0x303040;
   headMaterial.ambient = 1;
   } 

However, does anyone know how to load a 3D Object with multiple textures?

Are you using modelling software to export the OBJ file? The textures can be applied in the modelling software and exporting out. As well as the OBJ file, there should be an accompanying MTL file that loads the required textures. Just ensure the MTL file uses paths relative to the swf export. To load this, you could use:

AssetLibrary.enableParser(OBJParser);
AssetLibrary.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
AssetLibrary.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onFullyLoaded);
AssetLibrary.loadData(new MyOBJModel());

Thank you.

Ive changed the section to the following:

private function init(_view, _scene):void
  {
   var view = _view;
   var scene = _scene;
   
   Parsers.enableAllBundled()
   
   function initObjects():void
   {
    //default available parsers to all
    AssetLibrary.enableParser(OBJParser);
    AssetLibrary.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
    AssetLibrary.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onFullyLoaded);
    AssetLibrary.loadData(new _myobj());    
   }
   
   function onFullyLoaded(evt:LoaderEvent):void
   {
    scene.addChild(_myobj);
   }
   
   function onAssetComplete(evt:AssetEvent):void
   {
    
   }
   
  } 

I am still new to away3d.

What do I do with the assets? How would I apply it to the object?
(onAssetComplete)

I truly appreciate the help.

function onAssetComplete(evt:AssetEvent):void
{
    if (evt.asset.assetType == AssetType.MESH) {
      var mesh:Mesh = evt.asset as Mesh;
      scene.addChild(mesh);
      var material:TextureMaterial = TextureMaterial(mesh.material);
   }
 } 

That would add the objects to the scene as they loaded. If you need to modify the material, you can select that also.

If I add


scene.addChild

to both ‘onFullyLoaded’ and ‘onAssetComplete’, wont I be adding the object to the scene twice?

Im confused. What I’m trying to accomplish is just having a .OBJ file loaded as-is, without modifying the textures, for now.

From your code, I’m not sure what your OBJ variable is called. Remove the addChild from onFullyLoaded for now and see if it works.

Oh, here’s the full code to this class:

I commented out the scene.addChild in onFullyLoaded and I get this error:

This is a pic of the obj im trying to load.

Anyone? Pls? It seems like I’m so close! I just need to understand how to load it properly and I can go on from there.

Please, can anyone help me?

I need to successfully import/load 1 3d object and go from there. I’m having the toughest of times with Away3D.4.

Comment out the reference to the material, do you still get an error?
And is onFullyLoaded being called?

I did as you said, and hmmm, it seems that onFullyLoaded is not kicking in.

function initObjects():void
   {
    //default available parsers to all
    AssetLibrary.enableParser(OBJParser);
    //AssetLibrary.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
    AssetLibrary.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onFullyLoaded);
    AssetLibrary.loadData(new _myobj());    
   }
   
   function onFullyLoaded(evt:LoaderEvent):void
   {
    scene.addChild(_myobj);
    var tod = stage.getChildByName('navigationMC');
    tod.alpha = 0;
   }
 
   /*function onAssetComplete(evt:AssetEvent):void
   {
    if (evt.asset.AssetType == AssetType.MESH)
    {
     var mesh:Mesh = evt.asset as Mesh;
     scene.addChild(mesh);
     var material:TextureMaterial = TextureMaterial(mesh.material);
    }
   }*/

Have you put a trace in just to make sure?

Posted: 12 April 2012 12:32 AM Total Posts: 73 [ # 13 ]

I put, in place of trace the following code:

var tod = stage.getChildByName('navigationMC');
    tod.alpha = 0; 

I used trace at first too.

Both do nothing as onFullyLoaded is not called, and Im wondering why.

(I appreciate the help, Donny).

Looking back at the code you posted previously, how are you calling initObjects()? Why is this method nested within init() too?

Oops. I was deleting code and adding to test. I guess I forgot to add the initObjects back. I added it back and ran the code again, and nothing still. No errors and onFullyLoaded isnt called.

I nested inside of init() to pass the scene and view to be used by the object.

The goal is to load the object, then onFullyLoaded, add the object to the current view/scene.

I also modeled the init() function after the away3d examples, for learning purposes.

The code is below, with initObjects included.

Load 3D Object with Multiple Textures Software: Away3D 4.x
