本文详细介绍了一种在Unity中实现双面不同效果渲染的技术，通过定制Shader来分别控制正反面的光照、颜色和透明度，适用于特殊视觉效果的游戏开发。

思路

Surface不能像顶点/片元着色器一样用两个PASS

Call back
渲染正面的代码
Call front
渲染反面的代码

代码

Shader "Unlit/shader1"
{
Properties
   {
       _MainTex ("Particle Texture", 2D) = "white" {}
       _RimColor ("Rim Color", Color) = (0.5,0.5,0.5,0.5)
       _InnerColor ("Inner Color", Color) = (0.5,0.5,0.5,0.5)
       _InnerColorPower ("Inner Color Power", Range(0.0,1.0)) = 0.5
       _RimPower ("Rim Power", Range(0.0,5.0)) = 2.5
       _AlphaPower ("Alpha Rim Power", Range(0.0,8.0)) = 4.0
       _AllPower ("All Power", Range(0.0, 10.0)) = 1.0
       _InnerAlphaBase ("Inner Alpha Base", Range(0.0, 1.0)) = 1.0

       _backMainTex ("backParticle Texture", 2D) = "white" {}
       _backRimColor ("backRim Color", Color) = (0.5,0.5,0.5,0.5)
       _backInnerColor ("backInner Color", Color) = (0.5,0.5,0.5,0.5)
       _backInn
