d3d11 hook + cofm shader replacement
  1. compile dxgi.c & d3d11.c files - these create dxgi.dll and d3d11.dll that allows to dump & replace shaders.
cl.exe /nologo /O2 /W3 /MT dxgi.c /link /DLL /OUT:dxgi.dll /INCREMENTAL:NO kernel32.lib user32.lib
cl.exe /nologo /O2 /W3 /MT d3d11.c /link /DLL /OUT:d3d11.dll /INCREMENTAL:NO kernel32.lib user32.lib d3dcompiler.lib dxguid.lib shlwapi.lib

  1. put dxgi.dll and d3d11.dll files next to ChildrenOfMorta.exe

  2. create d3d11_shaders folder next to ChildrenOfMorta.exe and put ps_b1c05ceb9ca8a14c.hlsl into this folder.
