Need Guidance for Hairworks...

So what is the deal with Nvidia Hairworks? Somebody had told me that you need to manually integrate Nvidia gameworks into the source code yourself in order to use it? I was under the impression that it was already integrated into the source code? Sorry to bring up such a redundant topic. However, I’m having trouble figuring out how to get my mesh covered in Fur in Unreal.

I used Hair and Fur modifier in Max to groom my model. I then had the mesh rigged in Maya. I quickly found out that I needed to re-groom the mesh in Maya so I can get my rigged mesh into the engine with Fur. So I exported the Splines from Max as Curves for Maya. I tried reattaching the curves onto the rigged mesh in Maya. I’m now trying to figure out what to do from here.

Anyway, the details are not as important. What I am really wondering is, is Hairworks basically plug and play, or do I need to mess with the source code?
