在 DirectX11 顶点和像素着色器之间交换

Question

所以我一直在关注 Frank Luna 书中“使用 DirectX11 进行 3D 游戏编程”中的教程，并且一直在研究 Sky-box。除了纹理所需的小调整外，这个天空盒正在正确渲染。我为天空盒创建了一个单独的顶点和像素着色器，因为它不需要在 .fx 文件中进行太多工作。当我绘制对象时，它们都会绘制，但是当我使用正常工作的正常顶点和像素着色器时，我的对象显示为黑色（我认为它们无法从着色器中获取颜色）。

_pImmediateContext->RSSetState(_solidFrame);
_pImmediateContext->VSSetShader(_pSkyVertexShader, nullptr, 0);
_pImmediateContext->PSSetShaderResources(3, 1, &_pTextureSkyMap);
_pImmediateContext->PSSetShaderResources(0, 1, &_pTextureRV);
_pImmediateContext->PSSetShaderResources(1, 1, &_pSpecTextureRV);
_pImmediateContext->PSSetShaderResources(2, 1, &_pNormTextureRV);
_pImmediateContext->PSSetSamplers(0, 1, &_pSamplerLinear);
_pImmediateContext->PSSetShader(_pSkyPixelShader, nullptr, 0);

//Imported Sky
world = XMLoadFloat4x4(&_sky.GetWorld());
cb.mWorld = XMMatrixTranspose(world);
_pImmediateContext->UpdateSubresource(_pConstantBuffer, 0, nullptr, &cb, 0, 0); //Copies the constant buffer to the shaders.
//Draw the Pitch
_sky.Draw(_pd3dDevice, _pImmediateContext);

_pImmediateContext->VSSetShader(_pVertexShader, nullptr, 0);
_pImmediateContext->VSSetConstantBuffers(0, 1, &_pConstantBuffer);
_pImmediateContext->PSSetConstantBuffers(0, 1, &_pConstantBuffer);
_pImmediateContext->PSSetShaderResources(0, 1, &_pTextureMetalRV);
_pImmediateContext->PSSetShaderResources(1, 1, &_pSpecTextureRV);
_pImmediateContext->PSSetShaderResources(2, 1, &_pNormTextureRV);
_pImmediateContext->PSSetSamplers(0, 1, &_pSamplerLinear);
_pImmediateContext->PSSetShader(_pPixelShader, nullptr, 0);

//Floor
// Render opaque objects //
// Set vertex buffer for the Floor
_pImmediateContext->IASetVertexBuffers(0, 1, &_pVertexBufferFloor, &stride, &offset);
// Set index buffer
_pImmediateContext->IASetIndexBuffer(_pIndexBufferFloor, DXGI_FORMAT_R16_UINT, 0);
world = XMLoadFloat4x4(&_worldFloor);
cb.mWorld = XMMatrixTranspose(world);
_pImmediateContext->UpdateSubresource(_pConstantBuffer, 0, nullptr, &cb, 0, 0); //Copies the constant buffer to the shaders.
_pImmediateContext->DrawIndexed(96, 0, 0);

//Imported Pitch
world = XMLoadFloat4x4(&_pitch.GetWorld());
cb.mWorld = XMMatrixTranspose(world);
_pImmediateContext->UpdateSubresource(_pConstantBuffer, 0, nullptr, &cb, 0, 0); //Copies the constant buffer to the shaders.
//Draw the Pitch
_pitch.Draw(_pd3dDevice, _pImmediateContext);

_pImmediateContext->PSSetShaderResources(0, 1, &_pTextureMetalRV);
_pImmediateContext->PSSetShaderResources(1, 1, &_pSpecTextureMetalRV);
_pImmediateContext->PSSetShaderResources(2, 1, &_pNormTextureMetalRV);

我是否遗漏了一行代码来清除更改着色器和不使用错误数据之间的某些内容？？

对我没有注意到的 .fx 文件进行小幅编辑是个问题。现在通过恢复该文件来修复。
