I have just compiled directly from my branch and it all compiles mine and the hairworks, If anyone else can compile and check : https://github/kingbobski/UnrealEngine/tree/patch-1
I have no with it but two other people have, If we could get a few more people to compile it, I have also checked my own UE4 fork (On my private server) and i have not done any other fixes other the ones in the pull requests… I think it will be a prerequisite but currently unknown!
Hope you guys enjoy it if we can get it all working! 
looks fantastic! Thanks for the link, I just hope Nvidia get into their UE branch ASAP!
Have you tried completely disabling the AMD card, I just have a Nvidia card and it’s all good! Also I would not exactly make a core gameplay mechanic to be Flex because that will then an Nvidia Exclusive game! But if that’s how you want to do it!
