I want to clone a model loaded with loader, I found this issue on github,but the solution doesn\'t work. It seems there has been an structural change in Object3D.

I found one fast solution (not the most efficient)

The GLTFLoader uses the THREE.FileLoader() method internally, which allows you to cache files.
To do so, you need to add this line before you create an instance of the GLTFLoader

THREE.Cache.enabled = true;

Then you can load multiple times the same model, but only the first time will take longer, for example:

THREE.Cache.enabled = true;

var loader = new GLTFLoader();

var deeplyClonedModels = [];

for( var i = 0; i < 10; i++ ){

   loader.load('foo.gltf', function ( gltf ) {

     deeplyClonedModels.push(gltf.scene);

  });

}
