After some struggles described in another thread, I got my program doing MSAA on Mac with Metal. But when I try it on Windows (32-bit) with the Direct3D11 rendering system, I get an exception. Here's Ogre.log:

14:01:49: OGRE EXCEPTION(3:RenderingAPIException): D3D11 device cannot draw
Error Description:ID3D11DeviceContext::Draw: The Pixel Shader expects a Render Target View bound to slot 0, but none is bound. This is OK, as writes of an unbound Render Target View are discarded. It is also possible the developer knows the data will not be used anyway. This is only a problem if the developer actually intended to bind a Render Target View here.
Active OGRE shaders:
VS = Ogre/Compositor/Quad_vs_HLSL
FS = JW/DepthResolve_ps_hlsl in D3D11RenderSystem::_render at D:\MoreCode\Ogre\ogre-next-fork\RenderSystems\Direct3D11\src\OgreD3D11RenderSystem.cpp (line 3177)The compositor node in which the problem happens:

target resolvedDepth
{
pass render_quad
{
load { all dont_care }
material JWResolveMSAADepth
input 0 msaaDepth

}
}
out 0 colorTx

}Here is the material script:

{
}
fragment_program_ref JW/DepthResolve_ps
{
}
texture_unit depth
{
tex_address_mode clamp
filtering none
}
}
}
}The HLSL implementation of the fragment shader is identical to the shader Resolve_1xFP32_Subsample0_ps.hlsl used in a couple of the Ogre sample programs:
Code: Select all
Texture2DMS<float> myTexture : register(t0);
struct PS_INPUT
{
float2 uv0 : TEXCOORD0;
};
float main
(
PS_INPUT inPs,
float4 gl_FragCoord : SV_Position
) : SV_Target
{
return myTexture.Load( int2( gl_FragCoord.xy ), 0 ).x;
}When the error message says that nothing is bound to slot 0, it sound like the shader is not receiving the MSAA depth texture that is supposed to be the input for this quad pass. But in a CompositorWorkspaceListener passPreExecute method, when I see the pass in question I do this
Code: Select all
const Ogre::CompositorNode* node = compPass->getParentNode();
Ogre::TextureGpu* depthInTex = node->getDefinedTexture("msaaDepth");and I can see in the debugger that depthInTex is a texture with the expected depth pixel format and number of samples. Can anyone help me understand the error?
