Outline effect not work(use with MeshToonMaterial)

Hi.

I wan’t to make toon feeling scene so I checked this example

First I loaded the glb file with MeshStandardMaterial, and then I changed all material to MeshToonMaterial.

As you can see the material changed to Toon material. But, I can’t make outlineEffect even I use this function.

            effect = new OutlineEffect(renderer);
             ...
            ...

    function animate() {
        requestAnimationFrame(animate);
       ....
        if (effect) effect.render(scene, currentCamera);
    }

What should I check to use outlineEffect?
