Unity动态创建带有Shader的Material

Unity5.x不在允许通过string的格式给材质添加shader，必须通过shaderAssets，否则警告：

UnityEngine.Material.Material(string) is obsolete:'Creating materials from shader source string is no longer supported. Use Shader assets instead.'

        具体操作方法：

1、添加一个Shader，放入工程中：

        

Shader "UI/Default Grey" {   Properties {    _MainTex ("Base (RGB)", 2D) = "white" {}    _Specular ("Specular", Range(1.0, 500.0)) = 250.0   }  ...

      2、创建一个材质

      

Material mat = new Material(Shader.Find("UI/Default Grey"));(img.GetComponent<Renderer>() as Renderer).material = mat;
