I’m trying to just only rerender local .obj model using OBJLoader and did’t add any changes to it. But what I got was not satisfying–There are some triangles around every circle while not the original one:

original:

what I got:

main code:

```
var loader = new THREE.OBJLoader();
loader.load("star.obj", function (object) {
object.traverse( function ( child ) {
if (child instanceof THREE.Mesh) {
var simplify = new THREE.Geometry().fromBufferGeometry(child.geometry);
simplify.computeFaceNormals();
simplify.mergeVertices();
simplify.computeVertexNormals();
material = new THREE.MeshNormalMaterial();
mesh = new THREE.Mesh(simplify, material);
mesh.scale.set(6, 6, 6);
scene.add(mesh);
}
});
});
```

Any way to solve this?
