The TressFX repository here: https://github.com/GPUOpen-Effects/TressFX provides sample implementations of TressFX 4.1 in DX12 and Vulkan. I am aiming to implement either 4.0 or 4.1 in an existing DX11 engine. While the documentation for 4.1 does not explicitly mention DX11, it also does not indicate that support for DX11 has been completely dropped. Would implementing TressFX 4.1 in DX11 be doable by porting DX12EngineInterfaceImpl.cpp to DX11, or is there a hard incompatibility between DX11 and TressFX 4.1?
