如何讓模型產生雙面法線效果

來源:互聯網

在Unity的內建shader中,預設的顯像方式是 "Back-Face Culling",也就是背面是看不見的,如果需要呈現雙面法線時,我們可以透過修改Shader來達到正反面都顯示的效果。

1.預設的顯示模式,反面是看不見的。

2.新增一個自訂shader檔案。

3.以內建的Diffuse為例,修改其中的Pass函數,增加一行 "Cull Off"。

4.新增一個材質球並套用修改過的shader,即可達到雙面顯像的效果。

 
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" = "PixelOrNone"}       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 }
