改变材料在三星电视上显示为粉红色

Question

我正在使用 Unitys build > Samsung TV 为三星电视制作应用程序。

我有一堆原始框，其中我已将材质 mainTexture 更改为图集，并将网格过滤器 uv 更改为 PackTextures 方法中的给定 uv。

            Texture2D[] allCubeTextures = new Texture2D[] { app.GetComponentInChildren<Image>().mainTexture as Texture2D, Resources.Load<Texture2D>("Black"), Resources.Load<Texture2D>("Black"), Resources.Load<Texture2D>("Black"), Resources.Load<Texture2D>("Black"), Resources.Load<Texture2D>("Black") };
            Texture2D textureAtlas = new Texture2D(2, 2);
            Rect[] atlasUvs = textureAtlas.PackTextures(allCubeTextures, 200);
            icon.GetComponent<Renderer>().material.mainTexture = textureAtlas;
            Vector2[] uv = new Vector2[6 * 4];
            for (int i = 0; i < atlasUvs.Length; i++)
            {
                int j = i * 4;
                uv[j] = new Vector2(atlasUvs[i].xMin, atlasUvs[i].yMin);
                uv[j + 1] = new Vector2(atlasUvs[i].xMax, atlasUvs[i].yMin);
                uv[j + 2] = new Vector2(atlasUvs[i].xMin, atlasUvs[i].yMax);
                uv[j + 3] = new Vector2(atlasUvs[i].xMax, atlasUvs[i].yMax);
            }
            Mesh mesh = icon.GetComponent<MeshFilter>().mesh;
            mesh.uv = uv;

在编辑器中看起来一切都很好，但是，每当我在三星电视上测试时，这些盒子都是粉红色的（好像它们是坏掉的着色器）。

在将 mainTexture 编辑为图集纹理之前，我使用了统一标准 uv。这行得通，但我的纹理是四面八方的，而不是我的图集现在如何处理它。这就是为什么我认为它可能与此有关。

为了解决这个错误，我还尝试了一堆不同的着色器，但没有不同的结果。

只是三星电视不支持我的纹理的这种实现吗？

编辑： 在做了一些进一步的挖掘之后，我认为我的问题与： Textures loads in editor but not in standalone (appears pink) 我不太明白解决方案。选择预加载着色器时，我别无选择。另外，我使用的是标准着色器，所以我认为这不是问题。

编辑 2： 好的，经过更多研究后，我发现了这篇文章：http://answers.unity3d.com/questions/939160/getting-pink-textures-in-build.html 看来我必须将我的着色器（Unlit/Texture）添加到始终包含的着色器中。但是，这只会将框更改为白色而不是粉红色。正如 Legacy/Diffuse 所做的那样，它也在始终包含的着色器中。

Answer 1

我注意到三星电视日志中有一行：-------- Shader compilation failed 您的着色器编译失败，所以粉红色的东西是预期的行为。

着色器可以在设备上编译和运行良好，但在其他设备上失败。这很正常。如果您使用的是内置标准着色器，请向 Unit 报告错误，否则请在支持 SamsungTV 设备的着色器中包含子着色器。

这部分也要注意：

fragment evaluation shader
0:4: P0003: Extension 'GL_EXT_frag_depth' not supported
0:6: P0004: High precision not supported, instead compiling high precision as medium precision
0:38: L0002: Undeclared variable 'gl_FragDepthEXT'
Note: Creation of internal variant of shader 'Hidden/Internal-MotionVectors' failed.
WARNING: Shader Unsupported: 'Hidden/Internal-MotionVectors' - Pass '' has no vertex shader
WARNING: Shader Unsupported: 'Hidden/Internal-MotionVectors' - Setting to default shader.

据我所知，您的着色器使用了一个名为 GL_EXT_frag_depth 的不受支持的库，这会导致该类型的变量 gl_FragDepthEXT 未声明。

Answer 2

好的，所以我找到了解决方案。

正如编辑 1 中的链接中所写，我必须将着色器都包含在“编辑”>“项目设置”>“图形”下的“始终包含的着色器”中。 然后我必须将 ShaderVariant 保存到我的资产文件夹，并将该变体添加到“Shader Preloading”中。
