Shader学习过程8——5.x以前的SurfaceShader

Shader "Custom/SurfaceShader" {
	Properties {
		_Color ("Color", Color) = (1,1,1,1)
		_MainTex ("Albedo (RGB)", 2D) = "white" {}
		
	}
	SubShader {
		Tags { "RenderType"="Opaque" }
		LOD 200
		
		CGPROGRAM
		
		#pragma surface surf Lambert fullforwardshadows
		#pragma target 3.0

		sampler2D _MainTex;

		struct Input {
			float2 uv_MainTex;

		fixed4 _Color;
		void surf (Input IN, inout SurfaceOutput o) {
			fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color;
			o.Albedo = c.rgb;
			o.Alpha = c.a;
