I have couple more questions that sprung to mind while I was thinking of how to link materials with the effect/cbuffer system.
1) If the CBuffer structures are so minimal how do you determine what buffer register to bind them to when creating the bind commands for the state groups in your materials, etc? (assuming you only store the buffer register index in the CBufferInfo class and not in your CBuffer classes)
One option I thought was that the position in the vector of cbuffers would be the register index but then realised that wouldn't work because the vector contains buffers from all shaders types and so you could have vector items 0,1 = {vs_b0, vs_b1} and items 2,3 = {ps_b0, gs_b0}.
2) When dealing with DX11, at what point do you create the actual buffer resources and how do you store/link them with the emulated cbuffer structure?
As for designing a material format, I was thinking each material would get a copy of all the default cbuffers from the effect/shader it holds and then use the material specification to determine what cbuffer constants to lookup and change. Is this essentially what you do in your system?
