I had finished blend something into scene color texture like this:
FPostOpaqueRenderDelegate PostOpaqueRender;
PostOpaqueRender.BindLambda(
[this](FPostOpaqueRenderParameters& p)
{
this->ExecutePixelShaderInternal();//Render Code,just some C++ and HLSL
}
);
GetRendererModule().RegisterPostOpaqueRenderDelegate(PostOpaqueRender);
....
ExecutePixelShaderInternal()
{
SetRenderTarget(RHICmdList, FSceneRenderTargets::Get(RHICmdList).GetSceneColorTexture(), FTexture2DRHIRef());
}
I found that void FSkeletalMeshSceneProxy::GetDynamicElementsSection collect and render the meshcomponents.
just like this:
if ( ensureMsgf(Mesh.MaterialRenderProxy, TEXT("GetDynamicElementsSection with invalid MaterialRenderProxy. Owner:%s LODIndex:%d UseMaterialIndex:%d"), *GetOwnerName().ToString(), LODIndex, SectionElementInfo.UseMaterialIndex) &&
ensureMsgf(Mesh.MaterialRenderProxy->GetMaterial(FeatureLevel), TEXT("GetDynamicElementsSection with invalid FMaterial. Owner:%s LODIndex:%d UseMaterialIndex:%d"), *GetOwnerName().ToString(), LODIndex, SectionElementInfo.UseMaterialIndex) )
{
Collector.AddMesh(ViewIndex, Mesh);
}
const int32 NumVertices = Chunk.NumRigidVertices + Chunk.NumSoftVertices;
INC_DWORD_STAT_BY(STAT_GPUSkinVertices,(uint32)(bIsCPUSkinned ? 0 : NumVertices));
INC_DWORD_STAT_BY(STAT_SkelMeshTriangles,Mesh.GetNumPrimitives());
INC_DWORD_STAT(STAT_SkelMeshDrawCalls);
As you see, I’d been stopped here.I can’t get the vertex data for doing something like C++ with HLSL.
Do someone know how to get mesh data for another rendering pipeline?
