A Quick one. I have an effect that only write to depth.
commandList->OMSetRenderTargets(0, nullptr, FALSE, &m_mainDepthStencilDescriptorHandle.getCpuHandle());

Pixel shader look like this

struct VS_OUTPUT
{
    float4 position: SV_POSITION;
};

float4 main(VS_OUTPUT input) : SV_TARGET
{
    return float4(0.0f, 0.0f, 0.0f, 0.0f);
}

I do not use the SV_TARGET i am only interested in depth writting. What is the proper way to tell HLSL about it?
