When setting values on materials using the Standard Shader, you should be aware that you may need to use EnableKeyword to enable features of the shader that were not previously in use. For more detail, read Accessing Materials via Script.

当设置材质使用Standard Shader的颜色值时，你应该意识到，需要使用EnableKeyword来启用以前未使用过的shader的属性。

JavaScript:

var rend: Renderer;
 
 
function Start () {
	rend = GetComponent.<Renderer>();
 
	// Use the Specular shader on the material
	rend.material.shader = Shader.Find("Specular");
}
 
 
function Update () {
	// Animate the Shininess value
	var shininess : float = Mathf.PingPong(Time.time, 1.0);
	rend.material.SetFloat("_Shininess", shininess);
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Renderer rend;
    void Start() {
        rend = GetComponent<Renderer>();
        rend.material.shader = Shader.Find("Specular");
    }
    void Update() {
        float shininess = Mathf.PingPong(Time.time, 1.0F);
        rend.material.SetFloat("_Shininess", shininess);
    }
