I'm trying to get MeshNormalMaterial to stay aligned with the object rather than the camera. As far as I know, setting .normalMapType = THREE.ObjectSpaceNormalMap is supposed to do this. However it isn't.
Is there something I'm missing or an alternative in order to make this work?
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;
camera.position.applyAxisAngle(new THREE.Vector3(1, 0, 0), 0.3);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
window.addEventListener('resize', () => {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize(window.innerWidth, window.innerHeight);
}, false);
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshNormalMaterial();
material.normalMapType = THREE.ObjectSpaceNormalMap;
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);
const controls = new THREE.OrbitControls(camera, renderer.domElement);
controls.update();
function animate() {
requestAnimationFrame(animate);
//cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
controls.update();
renderer.render(scene, camera);
};
animate();body { margin: 0; overflow: hidden; background: black; }<script src="https://unpkg.com/three@0.140.2/build/three.js"></script>

normalMapType determines the type of normal map (tangent vs. object-space). You are not using a normal map so this property is unrelated to your use case.
The effect you are trying to achieve can't be configured with MeshNormalMaterial. You have to implement a custom shader by yourself.
