D3D11: WARNING: ID3D11DeviceContext::OMSetRenderTargets: Resource being set to OM RenderTarget slot 0 is still bound on input! [ STATE_SETTING WARNING #9: DEVICE_OMSETRENDERTARGETS_HAZARD ]
D3D11: WARNING: ID3D11DeviceContext::OMSetRenderTargets[AndUnorderedAccessViews]: Forcing PS shader resource slot 0 to NULL. [ STATE_SETTING WARNING #7: DEVICE_PSSETSHADERRESOURCES_HAZARD ]
I have tracked it down to the line that is printing this warning, and the line that is causing this to happen.
I am trying to achieve rendering to a texture, then to display the texture. While I do know how to do this, I do not know how to prevent these warnings. The warning will display after I the second time this line will get called.
m_pD3D11DeviceContext->OMSetRenderTargets(1, &m_renderTargetView,
m_pDepthStencilView);
It is a result of inside TextureShaderClass::SetShaderParameters where this line is called
deviceContext->PSSetShaderResources(0, 1, &texture);
My main rendering loop looks like this, and yes, there is no actual contents being rendered, I am trying to break this bug down to the smallest bit possible.
void Render()
{
// Render to texture initialize
{
// Set the Render Target to be the render to texture.
m_pD3D11DeviceContext->OMSetRenderTargets(1, &m_renderTargetView,
m_pDepthStencilView);
float color[4];
color[0] = 0.0f;
color[1] = 0.0f;
color[2] = 1.0f;
color[3] = 1.0f;
// Clear the render to texture
m_pD3D11DeviceContext->ClearRenderTargetView(m_renderTargetView, color);
m_pD3D11DeviceContext->ClearDepthStencilView(m_pDepthStencilView,
D3D11_CLEAR_DEPTH, 1.0f, 0);
}
// Reset the render target back to the original back buffer and not the render to texture anymore.
m_pD3D11DeviceContext->OMSetRenderTargets(1, &m_pD3D11RenderTargetView, m_pDepthStencilView );
// Clear the buffers to begin the scene
{
float color[4];
color[0] = 0.0f;
color[1] = 1.0f;
color[2] = 0.0f;
color[3] = 1.0f;
m_pD3D11DeviceContext->ClearRenderTargetView( m_pD3D11RenderTargetView, color );
m_pD3D11DeviceContext->ClearDepthStencilView( m_pDepthStencilView, D3D11_CLEAR_DEPTH, 1.0f, 0 );
}
// Turn off the Z buffer to begin all 2D rendering.
m_pD3D11DeviceContext->OMSetDepthStencilState(m_depthDisabledStencilState, 1);
// Render the texture at 50, 50
{
m_DebugWindow->Render(m_pD3D11DeviceContext, 50, 50);
D3DXMATRIX worldMatrix;
D3DXMatrixIdentity(&worldMatrix);
D3DXMATRIX viewMatrix;
D3DXMatrixIdentity(&viewMatrix);
m_TextureShader->Render(m_pD3D11DeviceContext, m_DebugWindow->GetIndexCount(),
worldMatrix, viewMatrix, m_orthoMatrix, m_shaderResourceView);
}
m_pD3D11DeviceContext->OMSetDepthStencilState(m_depthStencilState, 1);
m_pSwapChain->Present(0, 0);
}
There is two functions that get called in that, m_DebugWindow->Render and m_TextureShader->Render. I will first show the contents of m_TextureShader->Render as I do not believe m_DebugWindow->Render is causing the error.
bool TextureShaderClass::Render(ID3D11DeviceContext* deviceContext, int indexCount, D3DXMATRIX worldMatrix, D3DXMATRIX viewMatrix,
D3DXMATRIX projectionMatrix, ID3D11ShaderResourceView* texture)
{
bool result;
// Set the shader parameters that it will use for rendering.
result = SetShaderParameters(deviceContext, worldMatrix, viewMatrix, projectionMatrix, texture);
if(!result)
{
return false;
}
// Now render the prepared buffers with the shader.
RenderShader(deviceContext, indexCount);
return true;
}
Which calls these two functions
bool TextureShaderClass::SetShaderParameters(ID3D11DeviceContext* deviceContext, D3DXMATRIX worldMatrix, D3DXMATRIX viewMatrix,
D3DXMATRIX projectionMatrix, ID3D11ShaderResourceView* texture)
{
HRESULT result;
D3D11_MAPPED_SUBRESOURCE mappedResource;
ConstantBufferType* dataPtr;
unsigned int bufferNumber;
// Lock the constant buffer so it can be written to.
result = deviceContext->Map(m_constantBuffer, 0, D3D11_MAP_WRITE_DISCARD, 0, &mappedResource);
if(FAILED(result))
{
return false;
}
// Get a pointer to the data in the constant buffer.
dataPtr = (ConstantBufferType*)mappedResource.pData;
// Transpose the matrices to prepare them for the shader.
D3DXMatrixTranspose(&worldMatrix, &worldMatrix);
D3DXMatrixTranspose(&viewMatrix, &viewMatrix);
D3DXMatrixTranspose(&projectionMatrix, &projectionMatrix);
// Copy the matrices into the constant buffer.
dataPtr->world = worldMatrix;
dataPtr->view = viewMatrix;
dataPtr->projection = projectionMatrix;
// Unlock the constant buffer.
deviceContext->Unmap(m_constantBuffer, 0);
// Set the position of the constant buffer in the vertex shader.
bufferNumber = 0;
// Now set the constant buffer in the vertex shader with the updated values.
deviceContext->VSSetConstantBuffers(bufferNumber, 1, &m_constantBuffer);
// Set shader texture resource in the pixel shader.
deviceContext->PSSetShaderResources(0, 1, &texture);
return true;
}
void TextureShaderClass::RenderShader(ID3D11DeviceContext* deviceContext, int indexCount)
{
// Set the vertex input layout.
deviceContext->IASetInputLayout(m_layout);
// Set the vertex and pixel shaders that will be used to render this triangle.
deviceContext->VSSetShader(m_vertexShader, NULL, 0);
deviceContext->PSSetShader(m_pixelShader, NULL, 0);
// Set the sampler state in the pixel shader.
deviceContext->PSSetSamplers(0, 1, &m_sampleState);
// Render the triangle.
deviceContext->DrawIndexed(indexCount, 0, 0);
return;
}
If any more code is needed, please let me know. I have read the warnings, and the documentation for them, but I do not know how to prevent them. Does anyone know?
