场景上有个3转2的建筑模型，其中透明部分还是挡住了后面的怪物模型
shader是在Toon的基础上改的 代码是这样的
Shader "Cutoff Alpha"
{
Properties
{
_Color ("ColorSwitch", Color) = (1,1,1,1)
_ColorMain ("ColorMain", Color) = (1,1,1,1)
_OutlineColor ("Outline Color", Color) = (0,0,0,1)
_Outline ("Outline width", Range (.002, 0.03)) = 0.002
_MainTex ("Body (RGB)", 2D) = "white" { }
_MaskTex ("Mask", 2D) = "white" { }
_ToonShade ("ToonShader Cubemap(RGB)", CUBE) = "" { Texgen CubeNormal }
_TransVal ("Alpha", Range(0,1)) = 1
_UseSwitch ("UseSwitch", Range(0,1)) = 0
_Cutoff ("Alpha cutoff", Range(0,1)) = 0.5
}
SubShader
{
Tags { "LightMode"="ForwardBase" "RenderType"="Opaque" "Queue"="Transparent"}
Pass
{
Blend SrcAlpha OneMinusSrcAlpha

float4 cube = texCUBE(_ToonShade, i.cubenormal);

问下各位大神哪里写的有问题啊？
