Babylon.js删除了球体的光反射

Question

如何删除Babylon.js中球体（点）光的反射？

// Point light.
const light = new BABYLON.PointLight('myLight', new BABYLON.Vector3(0, 1, 0), scene)

// Sphere with size 100.
const newBox = BABYLON.Mesh.CreateSphere('mySphere', 64, 100, scene)

我想照亮半个球体，但没有红色圆圈的反射：

Answer 1

我找到了解决方案：

newBox.material = someMaterial
newBox.material.specularColor = new BABYLON.Color3(0, 0, 0);
