Unity3d 双面材质

Shader "Nature/Vegitation Vertex Lit" {

    Properties {

        _Color ("Main Color", Color) = (1,1,1,0)                           

        _SpecColor ("Spec Color", Color) = (1,1,1,1)       

        _Emission ("Emmisive Color", Color) = (0,0,0,0)   

        _Shininess ("Shininess", Range (0.01, 1)) = 0.7                        

        _FrontTex ("Front (RGB)", 2D) = "white" { }                            

        _BackTex ("Back (RGB)", 2D) = "white" { }

    }

    SubShader {

        Material {

            Diffuse [_Color]                                            

            Ambient [_Color]                                            

            Shininess [_Shininess]                                    

            Specular [_SpecColor]                                

            Emission [_Emission]                                    

        }

        Lighting On                                            

        SeparateSpecular On                                      

        Blend SrcAlpha OneMinusSrcAlpha                        

        Pass {

            Cull Front                                    

            SetTexture [_BackTex] {                            

                Combine Primary * Texture

            }

        } 

        Pass {

            Cull Back                                        

            SetTexture [_FrontTex] {                            

           







     Combine Primary * Texture

}}}}













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。
