Further note about FleX integration, FleX fluids, ropes, rigidbodies all work on my current 4.20 port, but I get crash whenever there is a softbody in the scene. I think it’s related to crashreport: https://issues.unrealengine/issue/UE-60339
For the time being, I think I’ll just wait what fix Epic pushes into 4.20.2 for (there wasn’t anything related on their 4.20 or dev branches yet).
Meanwhile, I’ve pushed work-in-progress version for UE 4.20.1 and FleX only :
https://github//UnrealEngi…/4.20-FleX
Just keep in mind that softbodies will cause hard crash on it + I never even tried to package with it as I wanted it to work in the editor first.
edit -> I also briefly looked into VXGI branch merge but it requires quite much work from the renderers side so I’ll not merge it for now. Same applies to HairWorks. I hope Nvidia will eventually push 4.20 versions on their UE4 forks, I can then do simple merge for the missing techs.
edit 2 -> FleX should run now, I’ve disabled the ue4 check that halted the execution, would need a better fix for FleX side of things though.
