DirectX 11透明混合缺少每一個其他紋素

Question

我想在directX 11中渲染透明像素，我不確定是否應該使着色或混合狀態自動執行此操作。 早些時候我認爲它是自動完成的，但我的透明紋理呈現爲一種純粹的顏色，忽略了每個紋理元素。 原始紋理是（7，7，7，139），渲染的顏色是（38，47，56，255）。

blendStateDescription.AlphaToCoverageEnable =     TRUE; 
blendStateDescription.IndependentBlendEnable =     FALSE; 
blendStateDescription.RenderTarget[0].BlendEnable =    TRUE; 
blendStateDescription.RenderTarget[0].BlendOp =     D3D11_BLEND_OP_ADD; 
blendStateDescription.RenderTarget[0].BlendOpAlpha =   D3D11_BLEND_OP_ADD; 
blendStateDescription.RenderTarget[0].SrcBlend =    D3D11_BLEND_SRC_ALPHA; 
blendStateDescription.RenderTarget[0].DestBlend =    D3D11_BLEND_INV_SRC_ALPHA; 
blendStateDescription.RenderTarget[0].SrcBlendAlpha =   D3D11_BLEND_ONE; 
blendStateDescription.RenderTarget[0].DestBlendAlpha =   D3D11_BLEND_ZERO; 
blendStateDescription.RenderTarget[0].RenderTargetWriteMask = D3D11_COLOR_WRITE_ENABLE_ALL; 

像素着色

float4 TexturePixelShader(PixelInputType input) : SV_TARGET { 
float4 textureColor; 
textureColor = shaderTexture.Sample(SampleType, input.tex); 
//discard pink for sprite transparency 
if(textureColor.r == 1.0f && textureColor.g == 0.0f && textureColor.b == 1.0f) { 
    discard; 
} 
//set the colour white as the specified pixel colour 
if(textureColor.r == 1.0f && textureColor.g == 1.0f && textureColor.b == 1.0f) { 
    textureColor = textureColor * pixelColor; 
} 
return textureColor; 
}

關閉AlphaToCoverage。這應該只用於多采樣效果圖。
