Currently using Origin Rebasing you can expand your worlds to the box of ±21 000 km in each direction.
I’ve developped a library of unreal engine vectors, transforms, rotations mostly converting FVector, FVector2D, FVector 3, FTransform, FQuat etc… to use and operate using double precision.
You first need to whange the Unreal Engine 4 Variable WORLD_MAX to go beyond the base ±20km of playable area.
