Direct3d 11深度模板 / Alpha混合问题

我一直在为游戏制作3D渲染器，直到现在，它首先使用drawIndexexed渲染了所有纹理网格和所有纹理网格。为了提高性能，我改用了DrawIndexedInstance，并制作了它，以便首先呈现纹理的网格，这揭示了如何设置Alpha混合和/或深度检查的问题。以下图像应说明问题是什么：

通过最前面纹理的顶部(首先渲染的纹理网格(查看

相同的视图，略有不同的角度(首先渲染的无纹理网格(

在前景和背景中是纹理矩形网的行，前景中的矩形网络具有部分透明的网格。在中间排是未纹理的网格，其透明度设置为0.3F。当首先呈现纹理网格时，未纹理的网格被前景中的透明网格遮盖了。但是，当首先渲染的不介入的网眼时，即使它们的透明度为0.3F，它们也完全掩盖了它们背后的纹理网格。当不介绍的网眼掩盖了其他未纹理的网格时，这不会发生这种情况，在这种情况下，Alpha混合起作用。

这是我设置栅格态，深度模板状态和深度模板视图的地方：

ID3D11Texture2D *pBackBuffer;
D3D11_TEXTURE2D_DESC backBufferDesc;
m_swapChain->GetBuffer(0, __uuidof(ID3D11Texture2D), (LPVOID*)&pBackBuffer);
pBackBuffer->GetDesc(&backBufferDesc);
RELEASE_RESOURCE(pBackBuffer);
// creating a buffer for the depth stencil
D3D11_TEXTURE2D_DESC depthStencilBufferDesc;
ZeroMemory(&depthStencilBufferDesc, sizeof(D3D11_TEXTURE2D_DESC));
depthStencilBufferDesc.ArraySize = 1;
depthStencilBufferDesc.BindFlags = D3D11_BIND_DEPTH_STENCIL;
depthStencilBufferDesc.CPUAccessFlags = 0; // No CPU access required.
depthStencilBufferDesc.Format = DXGI_FORMAT_D24_UNORM_S8_UINT;
depthStencilBufferDesc.Width = backBufferDesc.Width;
depthStencilBufferDesc.Height = backBufferDesc.Height;
depthStencilBufferDesc.MipLevels = 1;
depthStencilBufferDesc.SampleDesc.Count = 4;
depthStencilBufferDesc.SampleDesc.Quality = 0;
depthStencilBufferDesc.Usage = D3D11_USAGE_DEFAULT;
m_device->CreateTexture2D(&depthStencilBufferDesc, NULL, &m_depthStencilBuffer);
// creating a depth stencil view
HRESULT hr = m_device->CreateDepthStencilView(  m_depthStencilBuffer,
                                                NULL,   
                                                &m_depthStencilView);

// setup depth stencil state.
D3D11_DEPTH_STENCIL_DESC depthStencilStateDesc;
ZeroMemory(&depthStencilStateDesc, sizeof(D3D11_DEPTH_STENCIL_DESC));
depthStencilStateDesc.DepthEnable = TRUE;
depthStencilStateDesc.DepthWriteMask = D3D11_DEPTH_WRITE_MASK_ALL;
depthStencilStateDesc.DepthFunc = D3D11_COMPARISON_LESS;
depthStencilStateDesc.StencilEnable = FALSE;
hr = m_device->CreateDepthStencilState(&depthStencilStateDesc, &m_depthStencilState);
// setup rasterizer state.
D3D11_RASTERIZER_DESC rasterizerDesc;
ZeroMemory(&rasterizerDesc, sizeof(D3D11_RASTERIZER_DESC));
rasterizerDesc.AntialiasedLineEnable = FALSE;
rasterizerDesc.CullMode = D3D11_CULL_BACK;
rasterizerDesc.DepthBias = 0;
rasterizerDesc.DepthBiasClamp = 0.0f;
rasterizerDesc.DepthClipEnable = TRUE;
rasterizerDesc.FillMode = D3D11_FILL_SOLID;
rasterizerDesc.FrontCounterClockwise = FALSE;
rasterizerDesc.MultisampleEnable = FALSE;
rasterizerDesc.ScissorEnable = FALSE;
rasterizerDesc.SlopeScaledDepthBias = 0.0f;
// create the rasterizer state
hr = m_device->CreateRasterizerState(&rasterizerDesc, &m_RasterizerState);
m_deviceContext->OMSetRenderTargets(1, &m_renderTargetView, m_depthStencilView);
m_deviceContext->OMSetDepthStencilState(m_depthStencilState, 1);
m_deviceContext->RSSetState(m_RasterizerState);

这就是我启用alpha混合的地方：

D3D11_BLEND_DESC blendDescription;
ZeroMemory(&blendDescription, sizeof(D3D11_BLEND_DESC));
blendDescription.RenderTarget[0].BlendEnable = TRUE;
blendDescription.RenderTarget[0].SrcBlend = D3D11_BLEND_SRC_ALPHA;
blendDescription.RenderTarget[0].DestBlend = D3D11_BLEND_INV_SRC_ALPHA;
blendDescription.RenderTarget[0].BlendOp = D3D11_BLEND_OP_ADD;
blendDescription.RenderTarget[0].SrcBlendAlpha = D3D11_BLEND_ONE;
blendDescription.RenderTarget[0].DestBlendAlpha = D3D11_BLEND_ZERO;
blendDescription.RenderTarget[0].BlendOpAlpha = D3D11_BLEND_OP_ADD;
blendDescription.RenderTarget[0].RenderTargetWriteMask = D3D11_COLOR_WRITE_ENABLE_ALL;
m_device->CreateBlendState(&blendDescription, &m_blendState);
m_deviceContext->OMSetBlendState(m_blendState, 0, 0xffffffff);

我知道，给无纹理的网眼纯白色完全不透明的纹理会以某种方式解决该问题，但我怀疑深度测试是错误的。

当我使用d3d11_create_device_debug标志创建设备时，它不会给我任何错误或警告。

创建功能返回的所有hresults均为s_ok。

预先感谢。
