Question

目前我正在创建我的网格并对其进行纹理化。这可以从一方面起作用，但从另一方面起作用。

        m.name = "TopWallMesh";
        m.vertices = new Vector3[] {
            new Vector3(-width, 0f, -height),
            new Vector3(width, 0f, -height),
            new Vector3(-width, 0.1f, -height),
            new Vector3(width, 0.1f, -height)
        };
        m.uv = new Vector2[] {
            new Vector2 (0, 0),
            new Vector2 (0, 1),
            new Vector2 (1, 0),
            new Vector2 (1, 1)
        };
        m.triangles = new int[] { 0, 1, 2, 1, 3, 2 };
        m.RecalculateNormals();

如何解决此问题，使其双方都有纹理？

将Cull设置为关闭到着色器以渲染背面。这里有一个doubleside标准着色器的例子：

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" = "Always" /* Upgrade NOTE: changed from PixelOrNone to Always */}
     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
}

如何在Unity3D中纹理网格的两边？
