效果	效果	官方案例

区别：官方的案例更像一个镜子没有纹理等属性也没有透明度修改

根据源码进行修改为 MeshStandardMaterial实现反射

使用案例

createReflector() {const plane = this.helper.create.plane(2, 2);this.helper.add(plane.mesh);plane.mesh.rotateX(Math.PI / -2);plane.mesh.position.y -= 0.5;const material = plane.mesh.material;console.log(material);plane.mesh.material = new THREE.MeshStandardMaterial({map: this.helper.loadTexture("/public/textures/wallhaven-kxj3l1_840x840.png",(t) => {t.colorSpace = THREE.SRGBColorSpace;}),transparent: true,opacity: 0.3,});addReflectorEffect(plane.mesh);{const plane = this.helper.create.plane(100, 100);this.helper.add(plane.mesh);plane.mesh.rotateY(Math.PI / 2);plane.mesh.position.x -= 1.5;plane.mesh.material = new THREE.MeshStandardMaterial({map: this.helper.loadTexture("/public/textures/building.png",(t) => {t.colorSpace = THREE.SRGBColorSpace;}),normalMap: this.helper.loadTexture("/public/textures/wallhaven-kxj3l1_840x840.png",(t) => {t.colorSpace = THREE.SRGBColorSpace;}),});addReflectorEffect(plane.mesh);}}
