Hi,
is there still a problem parsing “big” obj files? I have two very similar files…one is around 1.5MB and is parsed perfectly the other one is around 3.0MB and isn’t displayed.

Loader3D.enableParser(OBJParser);
   //Parsers.enableAllBundled()
   _loader = new Loader3D();
   _loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onResourceComplete);
   _loader.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
   _loader.addEventListener(AssetEvent.MESH_COMPLETE, onMeshComplete);
   _loader.load(new URLRequest(fileName)); 

The files are attached.

Just tried. They both load without a hitch.

The problem is:
if i do the following:

Loader3D.enableParser(OBJParser);
   _loader = new Loader3D();
  //_loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onResourceComplete);
   //_loader.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
   //_loader.addEventListener(AssetEvent.MESH_COMPLETE, onMeshComplete);
   _loader.load(new URLRequest(fileName));
   
   _view.scene.addChild(_loader); 

The file is loaded completely and displayed correctly. But when i enable the “onResourceComplete” Event, to set the material of each loaded mesh inside a loop, i get only each second mesh.

private function onResourceComplete(event : LoaderEvent) : void
  {
    var mesh : Mesh;
    var objectsContainer:ObjectContainer3D = new ObjectContainer3D;
   if (_loader.numChildren  > 0)
   {
    var i : int = 0;
    while ( i < _loader.numChildren) 
    {
     
     mesh = Mesh(_loader.getChildAt(i));
     
     mesh.material = _material;
     mesh.geometry.scale(10);
     
     objectsContainer.addChild(mesh);
     i = i + 1;
     
    }
    
   }
   _scene.addChild(objectsContainer);
  } 

I put a screenshot of the result as attachment

Finally i fixed it. I just had to remove


_scene.addChild(mesh)
