Unity Shader Example 25 (在ShaderLab Surface 添加顶点颜色与透明效果)

Shader "Test" {
Properties {
_MainTex ("Base (RGB)", 2D) = "white" {}
}
SubShader {
Tags { "RenderType"="Opaque" }
LOD 150
ZWrite On
Blend SrcAlpha OneMinusSrcAlpha

CGPROGRAM
//#pragma surface surf Lambert noforwardadd

float4 vertexColor : COLOR;
};

void surf (Input IN, inout SurfaceOutput o) {

o.Albedo = c.rgb;
o.Alpha = c.a;
