Hi,

I recently built Nvidia’s Hariworks+UE4 from source and followed a simple tutorial on how to create a simple model to use in UE4. This model is consisted of a .FBX and .apx (hairworks file for hair) files. I can import both in UE4 and all seems fine. I followed this simple tutorial: [HairWorks Quick start Unreal Engine 4 Pipeline - YouTube](https://www.youtube.com/watch?v=09Oy92QGrQc)

My question is. How can I make those hairs be “linked” to the scene physics? For example, as show in the video at 9:04, tilting the plane where the hair/grass is makes them bend to the correct side.

I’m way too late but thought I’d answer in case someone sees this. Inside the hairworks asset you need to enable “simulate in world space”
