模糊着色器（Grab pass）在編輯器中顯示爲粉紅色，但在移動設備上工作

此着色器適用於移動設備，但在編輯器中顯示爲粉紅色。以前它工作正常，但不知何故，我建立移動後，然後開始顯示爲粉紅色。沒有錯誤，但它給我警告。我正在使用Unity 2017.2。模糊着色器（Grab pass）在編輯器中顯示爲粉紅色，但在移動設備上工作

我也嘗試重新打開項目。但仍然相同。

Shader "TFTM/Blur" { 
    Properties { 
    _blurSizeXY("BlurSizeXY", Range(0,10)) = 0 
} 
SubShader { 

    // Draw ourselves after all opaque geometry 
    Tags { "Queue" = "Transparent" } 

    // Grab the screen behind the object into _GrabTexture 
    GrabPass { } 

    // Render the object with the texture generated above 
    Pass {

      return sum/2;

} 

Fallback Off 
}

因爲它的，該材料不斷復位和在Unity編輯我不能查看和測試。

只要刪除#pragma target 4.0，它會正常工作。

所以，

#ifndef SHADER_API_D3D11 
     #pragma target 3.0 
#endif

編譯目標4.0與Mac不工作。（我正在使用IMac）
