Wireframe is off from model

Questions

Hi guys, I didnt fix it after all haha.
Made a quick low poly test and the wireframe is off again.
Everything works flawless except for the wireframe.

Either it is off by miles, or it is off a little, but it is not accurate as it should be.
Never had this problem with older versions of Babylon exporter (3ds max to gtLF).

Included a screenshot of the wireframe that is incorrect (works perfect with older models though) since the last Babylon plugin update (which might be coincidence) and my test model.

My wireframe code:
    if(wireframe == false) {

	storedOriginalModel.traverse(function(child) {

		if (child.isMesh) {

			// Extract current geometry and material
			let geometry = child.geometry;
			let material = child.material.color;

			// Setup our wireframe
			const wireframeGeometry = new THREE.WireframeGeometry(geometry);
			const wireframeMaterial = new THREE.LineBasicMaterial({color: 0xFFFFFF});
			const wireframe = new THREE.LineSegments(wireframeGeometry, wireframeMaterial);

			wireframe.name = 'wireframe';
			scene.add(wireframe);

		}

	});

    wireframe = true;

} else {

    scene.remove(scene.getObjectByName('wireframe'));

    wireframe = false;

}

Edit: Fixed it half… after making a wireframe in the above code I did this:

let geometry = child.geometry;
let position = child.position;
let rotation = child.rotation;
let scale = child.scale;

wireframe.position.x = position.x;
wireframe.position.y = position.y;
wireframe.position.z = position.z;

wireframe.rotation.x = rotation.x;
wireframe.rotation.y = rotation.y;
wireframe.rotation.z = rotation.z;

wireframe.scale.x = scale.x;
wireframe.scale.y = scale.y;
wireframe.scale.z = scale.z;

This works for almost all elements, but some elements are still off (grass for example).

Instead of adding the wireframe to the scene, add it to the mesh like so:

child.add( wireframe );

Good one, might be easier indeed, but besided that… how come everything is working fine except for 1 or 2 objects? is there any way to find out perhaps?

Not sure. I would need to debug the app to say more.
