unity3d双面材质创建教程

驰骋的风 3D打印店铺

在其它三维软件中设置好的双面材质导入到unity3d中就失去了效果，不过我们可以通过自定义材质来在unity3d中实现双面材质的效果。步骤如下：

1、在资源库中新建一新shader；

代码如下：



Normal

7.8 磅

false

Shader "DoubleSided" {

   Properties {

      _Color ("Main Color", Color) = (1,1,1,1)

      _MainTex ("Base (RGB)", 2D) = "white" {}

      //_BumpMap ("Bump (RGB) Illumin (A)", 2D) = "bump" {}

   }

   SubShader {      

      //UsePass "Self-Illumin/VertexLit/BASE"

      //UsePass "Bumped Diffuse/PPL"

      

      // Ambient pass

      Pass {

      Name "BASE"

      Tags {"LightMode" = "ixelOrNone"}

      Color [_PPLAmbient]

      SetTexture [_BumpMap] {

         constantColor (.5,.5,.5)

         combine constant lerp (texture) previous

         }

      SetTexture [_MainTex] {

         constantColor [_Color]

         Combine texture * previous DOUBLE, texture*constant

         }

      }

   

   // Vertex lights

   Pass {

      Name "BASE"

      Tags {"LightMode" = "Vertex"}

      Material {

         Diffuse [_Color]

         Emission [_PPLAmbient]

         Shininess [_Shininess]

         Specular [_SpecColor]

         }

      SeparateSpecular On

      Lighting On

      Cull Off

      SetTexture [_BumpMap] {

         constantColor (.5,.5,.5)

         combine constant lerp (texture) previous

         }

      SetTexture [_MainTex] {

         Combine texture * previous DOUBLE, texture*primary

         }

      }

   }

   FallBack "Diffuse", 1

}


然后在模型材质中更改shader为上面新建的Nature/Vegitation Vertex Lit这个shader即可实现双面效果。
