我试图指向对象的某些部分，整个对象都被指向了

Question

我试图指向对象的某个部分，整个对象都被指向了，我不知道是什么问题，我尝试了很多选择，我决定寻求帮助

GIf

代码

    function hoverPieces() {
      // Material
      const material = new THREE.MeshBasicMaterial({ color: 0xffff00 });
      raycaster.setFromCamera(mouse, camera);
      const intersects = raycaster.intersectObjects(scene.children, true);

      if (intersects.length > 0) {
        if (INTERSECTED != intersects[0].object) {
          if (INTERSECTED)
            INTERSECTED.material.emissive.setHex(INTERSECTED.currentHex);
          INTERSECTED = intersects[0].object;
          INTERSECTED.currentHex = INTERSECTED.material.emissive.getHex();
          INTERSECTED.material.emissive.setHex(0xff0000);
        }
      } else {
        if (INTERSECTED)
          INTERSECTED.material.emissive.setHex(INTERSECTED.currentHex);
        INTERSECTED = null;
      }
    }

如果需要对象（.glb）： https://wetransfer.com/downloads/54c0ef08f2fe2a4525388458ee175df220220223203644/3799a1

Answer 1

可以遍历，或者循环遍历gltf场景中的所有对象：

gltf.scene.traverse((object) => {
    if (object.material !== undefined) { //If there is no material on the object
        object.material = object.material.clone(); //clone the material
    }
});

就这些了！

I’m trying to point to some part of the object, the whole object is pointed
