在三星電視上顯示爲粉紅色的材料

Question

我正在爲三星電視製作應用程序，使用Unitys build> Samsung TV。

我有一堆原始框，我已經將材質mainTexture更改爲圖集，並將MeshFilters uv更改爲PackTextures方法中給定的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; 

它看起來在編輯器中所有好的和罰款，但是，每當我一個三星電視上測試，箱子都是粉紅色的（就好像它們是破着色器）。

在將mainTexture編輯爲地圖集紋理之前，我使用了統一標準uv。這工作，但我的紋理是四面八方，而不是我的地圖集現在處理它。這就是爲什麼我認爲這可能與此有關。

在我試圖圍繞這個錯誤包裹我的頭時，我也嘗試了一堆不同的着色器，沒有不同的結果。

三星電視不支持這種紋理實現嗎？

編輯： 做一些進一步的挖掘後，我想我的問題有所涉及： Textures loads in editor but not in standalone (appears pink) 我沒有完全得到解決，雖然。選擇preloded着色器時，我沒有選擇。此外，我使用標準着色器，所以我不認爲這會是一個問題。

編輯2： 好了，經過一些調查研究，我碰到這個帖子：http://answers.unity3d.com/questions/939160/getting-pink-textures-in-build.html 看來我要我的着色器（不亮/紋理）添加到總是包含着色器。然而，這只是將盒子變成白色而不是粉紅色。正如Legacy/Diffuse所做的那樣，因爲它也包含在始終包含的着色器中。

Answer 1

好的，所以我找到了解決方案。

如編輯1中的鏈接所寫，我不得不在「編輯>項目設置>圖形」下的「始終包含着色器」中包含着色器。 然後，我必須將ShaderVariant保存到我的資產文件夾，然後將該變體添加到「Shader預加載」中。

Answer 2

我注意到三星電視日誌中的一行：-------- Shader compilation failed 你的着色器編譯失敗，所以粉紅色的東西是一個預期的行爲。

着色器可以在設備上編譯和運行，但在其他設備上失敗。這很正常。如果您使用內置的標準着色器，請向Unit報告錯誤，否則在支持SamsungTV設備的着色器中包含SubShader。

注意這部分太：

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'

WARNING: Shader Unsupported: 'Hidden/Internal-MotionVectors' - Pass '' has no vertex shader 
WARNING: Shader Unsupported: 'Hidden/Internal-MotionVectors' - Setting to default shader. 

從我所看到的，你的着色器使用名爲GL_EXT_frag_depth不支持的庫，導致該類型未申報的變量gl_FragDepthEXT。
