As mentioned, I looked at it briefly, it would require bit too much of my time to port to 4.20 due to the engine changes on integration so I’m not porting it myself, but of course someone else might still do it. The techs I’ve ported didn’t require huge amount of work and that’s how they were selected now.
At stage I’m waiting for 4.20 HairWorks to appear on https://github/niexuchina/UnrealEngineHairWorks and the other GameWorks things at (they are still all at 4.19)
