Unreal Engine 4.21
Gravity Fields are areas where the gravitational force applies to all objects in their range. There are different kinds of gravity fields, like directional, centrifugal/centripetal, mirror repellent, cylinder centrifugal/centripetal, etc.
By implementing the gravity field, now making a cylinder world is possible in Unreal Engine, meaning players can move in one direction and go back to the origin. Other works like stepping resetting, light shading need to be updated as well.

Players can create and throw a “Black Hole“ to halt and pull objects towards its center. The realization is a powerful centripetal gravity field. In the demo below, you can see it halts the hound running towards the character:
