/home/windys/Development/UnrealEngine/Engine/Source/Runtime/Engine/Private/Particles/SubUVAnimation.cpp:5:10: fatal error: ‘ConvexHull2D.h’ file not found
#include “ConvexHull2D.h”

Some one know this problem!

Yep, it’s just a problem with case sensitive file systems. Go into the file with the error (SubUVAnimation.cpp) and replace the include statement for ConvexHull2D.h to ConvexHull2d.h
