I’ve been trying to load a .3DS model into an Away3D 4 project, but I am not able to load the texture from the model itself. I’ve seen a few posts regarding AssetLibrary, but those approaches have not worked for me. I’m able to load the .3DS model using the code below, but the model appears with a green color texture.

_loader = new Loader3D();
   _loader.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
   _loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onResourceComplete);
   _loader.load(new URLRequest('assets/skeleton.3DS')); 

private function onAssetComplete(event:AssetEvent): void {
   var newMaterial:ColorMaterial = new ColorMaterial(0xFF000);
   var mesh:Mesh = event.asset as Mesh;
   mesh.material = newMaterial; 
   mesh.scale(.25);
   mesh.rotationY = 90;
  } 

private function onResourceComplete(ev:LoaderEvent): void {
   view.scene.addChild(_loader);
  } 

I’ve also tried something like the code below within the onAssetComplete function, but I get a “Bad Input” error and a “A texture is bound on sampler 0 but not used by the fragment program.” error.

if (event.asset.assetType == AssetType.MESH) {
    mesh = Mesh(event.asset);
    //mesh.material = newMaterial; 
    mesh.scale(3);
    mesh.rotationY = 90;
    view.scene.addChild(mesh);
   }
   else if(event.asset.assetType == AssetType.MATERIAL) {
    mat = ColorMaterial(event.asset);
    //mesh.material = mat;
   } 

Any ideas?

I always assign my materials manually after loading, generally because I want to manipulate them. The routine I use is something like this…

public function loadModel(product:String):void {
   Loader3D.enableParser(Max3DSParser);
   _loader = new Loader3D();
   _loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onModelLoaded);
   _loader.load(new URLRequest("models/" + product)); 
   
   
   
  }
private function onModelLoaded(e : LoaderEvent) : void
  {

   _view.scene.addChild(_loader);
   
   var mat:ColorMaterial;
   mat =  new ColorMaterial(0xCCCCCC, 1);
   mat.lights = [_light];
   
   var i:int;
   var mesh:Mesh;
   var numChil:uint = _loader.numChildren;
   for (i = 0; i < numChil; ++i) {
    mesh = Mesh(_loader.getChildAt(i));
    //INSERT YOUR OWN CODE FOR MATERIAL, CHOOSE AFTER NAME, ETC.
    mesh.material = mat;
   }
   
  } 

Try something like that.

Good Luck!

Quick question, I’m getting an error at the first line within your loadModel function, it’s not liking OBJParserNamed. I see an OBJParser class, but not an OBJParserNamed class. Is this a custom class you created? Thanks for your help

Ah, you caught me
Yes, it’s a custom class so that meshes loaded in .obj format retain their mesh name. You can just remove it, as you’re using 3DS and so it’s not needed.
I’ll update the code in the post.

Ahh gotcha. I got the .3DS model loading using your example, I appreciate it!
