http://blog.csdn.net/candycat1992/article/details/17355629 這篇文章寫的很好，這里就直接上代碼了

Shader "Study/5_LambertDiffuse" {Properties{_Color("Main Color", Color) = (1,1,1,1)_MainTex("Base (RGB)", 2D) = "white" {}_EmissiveColor("Emissive Color", Color) = (1,1,1,1)_AmbientColor("Ambient Color", Color) = (1,1,1,1)_MySliderValue("This is a Slider", Range(0,10)) = 2.5}SubShader{Tags{ "RenderType" = "Opaque" }LOD 200CGPROGRAM #pragma surface surf Lambert MyLambertDiffusesampler2D _MainTex;fixed4 _Color;//We need to declare the properties variable type inside of the //CGPROGRAM so we can access its value from the properties block. float4 _EmissiveColor;float4 _AmbientColor;float _MySliderValue;struct Input{float2 uv_MainTex;};void surf(Input IN, inout SurfaceOutput o){//We can then use the properties values in our shader fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;c = c * pow((_EmissiveColor + _AmbientColor), _MySliderValue);o.Albedo = c.rgb;o.Alpha = c.a;}inline float4 LightingMyLambertDiffuse(SurfaceOutput s, fixed3 lightDir, fixed atten){float difLight = max(0, dot(s.Normal, lightDir));float4 col;col.rgb = s.Albedo * _LightColor0.rgb * (difLight * atten * 2);col.a = s.Alpha;return col;}ENDCG}FallBack "Diffuse" }

這個shader是包括了自發光和環境光效果的：

pow((_EmissiveColor + _AmbientColor), _MySliderValue);
