I have a spotlight. right under my 2 objects.
const light3 = new THREE.SpotLight(0xFFC8C8, 10, 0);
light3.position.set(0, -100, 0);
light3.castShadow = true;
One of the objects is a geometry created with a Shape and ExtrudeGeometry, then it is rotated and translated a bit.
This geometry is cloned, and the clone is translated over the green axis.
Finally the 2 geometries are merged using BufferGeometryUtils.mergeBufferGeometries(…)
The resulting geometry is turned into a mesh and added to the scene.
const mesh = new THREE.Mesh( geometry, new THREE.MeshStandardMaterial({
color: 0x111111,
emissive: 0x202020,
roughness: 0.5,
metalness: 0.9992,
side: THREE.DoubleSide,
}), );
mesh.receiveShadow = true;
scene.add( mesh );
I am wondering why both times have lighting, while the bottom object is in the way of the light rays to the upper object. Do I need to update something on the geometries before/after merging them ?
