collada file.I am embedding the dae file in the project

                                materials:
                                {
                                        monster: modelMaterial
                                },rotationY: -1
                        }
scene.addChild(colladaContainer);
                        var
animationData:AnimationData=colladaContainer.animationLibrary.getAnimation("default");
                        if(animationData!=null)
