hi. don’t know if this is still relevant, but I had the same issue and have found solution (not perfect though). Instead of /Yu you should write /YcYourProjectName.h /YuYourProjectName.h
Note that there is no space between /Yc and name, same for /Yu.
But after that you should use Unreal Editor to compile, because when using Build bttn in VS, there are errors.
p.s. sorry for english.
