It sounds like you are missing this info: The compiled HLSL shaders are not in the shader DLL. That DLL has the C++ code that does the state setup and linkage. The shaders themselves are in your mod directory under the shaders/ subdirectory. They are .VCS files. When you run the buildshaders command/process it produces those VCS files and header files that allow you to recompile your DLL and bind to the appropriate data/interfaces.
