Struggle with GLTF and lighting

[Mugen87]

Do you mind sharing the glTF asset in this thread?

@Oskawa

const renderer = new THREE.WebGLRenderer({
    antialias: true
});

renderer.toneMappingExposure = 2.3
renderer.shadowMap.enabled = true;
renderer.gammaFactor = 0;
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

For starters setup the renderer like so:

const renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.shadowMap.enabled = true;
renderer.outputEncoding = THREE.sRGBEncoding;
document.body.appendChild( renderer.domElement );
