Have you used NVIDIA VRWorks?

NVIDIA VRWorks is supported by Unreal.
(Https://developer.nvidia.com/nvidia-vrworks-and-ue4)

1. Introduction to VRWorks If you go to the homepage, you can easily use Unity Unreal Engine.
VRWorks is a sdk that can be used only with NVIDIA graphics card. I am wondering how to support Unreal Engine in a way other than writing dll, h file in visual studio like using library.

2. VRWorks searches Unreal documents, but no documentation is available. Click on the GitHub link on the above NVIDIA site
I can not find the page, and I will support it correctly.

3. Can I develop Oculus Lifts based on DirectX without using Unreal Engine? (Low Level)

Thank you(__)
