在unity中编辑3dMax或者Maya导入的模型时经常碰到一面显示一面透明的情况,主要是因为unity默认是不支持双面材质的,所以只需要自定义一个双面shader附加到材质上即可
实现步骤:
1. 在层次面板新建一个plane;
2. 新建一个yellow材质球并修改为黄色,然后添加到plane上。可以发现正面为黄色,而背面为透明的。
3. 在项目面板中新建一个shader,并命名为Doublesides。打开进行编辑下面代码:
Shader "Custom/DoubleSides" {
Properties {
_Color ("Color", Color) = (1,1,1,1)
_MainTex ("Albedo (RGB)", 2D) = "white" {}
_Glossiness ("Smoothness", Range(0,1)) = 0.5
_Metallic ("Metallic", Range(0,1)) = 0.0
}
SubShader {
Tags { "RenderType"="Opaque" }
LOD 200
Cull Off
CGPROGRAM
// Physically based Standard lighting model, and enable shadows on all light types
#pragma surface surf Standard fullforwardshadows
// Use shader model 3.0 target, to get nicer looking lighting
#pragma target 3.0
sampler2D _MainTex;
struct Input {
float2 uv_MainTex;
};
half _Glossiness;
half _Metallic;
fixed4 _Color;
void surf (Input IN, inout SurfaceOutputStandard o) {
// Albedo comes from a texture tinted by color
fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color;
o.Albedo = c.rgb;
// Metallic and smoothness come from slider variables
o.Metallic = _Metallic;
o.Smoothness = _Glossiness;
o.Alpha = c.a;
}
ENDCG
}
FallBack "Diffuse"
}
保存之后进入unity就能发现双面已经显示同样的材质。
