Can you try my branch? https://github//UnrealEngi…PR-FleX-4.19.2. branch used to build fine with VS2017 and has build fixes that are not present in the NvPhysX’s branch. I made a PR for the fixes but Nvidia ignored it time around (they accepted some similar PR I sent earlier), I’m guessing relevant people are just not following the PR’s at all.
There’s also 4.21 port : (credit to trashbyte for the 4.21 fixes).
