 const sunLight = new DirectionalLight(0xffffff, 0.2 * Math.PI); sunLight.position.set(120, 300, 200); // sunLight.castShadow = true; sunLight.shadow.mapSize.width = 4096; sunLight.shadow.mapSize.height = 4096; sunLight.shadow.camera.left = -40; sunLight.shadow.camera.right = 40; sunLight.shadow.camera.top = -40; sunLight.shadow.camera.bottom = 40; sunLight.shadow.camera.near = 0.5; sunLight.shadow.camera.far = 500; sunLight.shadow.bias = 0.0001 scene.add(sunLight);
