Incremental loading and mesh clone

[Hersir]

Hi, after loading incremental scene file on load finish I cloned one of mesh 

BABYLON.SceneLoader.Load("", scenePath, this.engine, (scene) => {
  scene.meshes.forEach((mesh) => {
     if(mesh.name === "m1") {
       mesh.clone("m2", mesh.parent, false, false);
       mesh.clone("m3", mesh.parent, false, false);
     }
  });
});

Probably it was not designed to work like that but every thing works as expected but I get console errors _this._delayLoadingFunction is not a function inside:

Mesh.prototype._queueLoad = function (mesh, scene) {
            var _this = this;
            scene._addPendingData(mesh);
            var getBinaryData = (this.delayLoadingFile.indexOf(".babylonbinarymeshdata") !== -1);
            BABYLON.Tools.LoadFile(this.delayLoadingFile, function (data) {
                if (data instanceof ArrayBuffer) {
                    _this._delayLoadingFunction(data, _this);
                }
                else {
                    _this._delayLoadingFunction(JSON.parse(data), _this);
                }
                _this.instances.forEach(function (instance) {
                    instance._syncSubMeshes();
                });
                _this.delayLoadState = BABYLON.Engine.DELAYLOADSTATE_LOADED;
                scene._removePendingData(_this);
            }, function () { }, scene.database, getBinaryData);
            return this;
};

Are you sure this only occurs when you are cloning the mesh? I'd have done the cloning exactly that way and don't see why it would cause this error

[Hersir]

@jschwuch Yes it related to cloning. I think that as mesh is loaded separately by time it is cloned file still loads and it tries to load it one more time for each clone and than have some collision.

@Hersir you could maybe try copying the ._delayLoadingFunction over to the new mesh, but I don't know if that would create any new problems... I'll sniff around the source a bit later today... really wouldn't expect this to happen.

@jschwuch No hurry I added clone just to debug some position changes, I don't need it for my final app, just found error and wanted to share it
