World composition 2 dimensional?

[Z-enzyme]

Qustion:

@Unreal Engine 4 Documentation

The World Composition editor supports shifting of the world origin by some arbitrary amount. Shifting the world origin results in adding an offset vector to all registered Actors in the world. Each Actor has an ApplyWorldOffset function which can be overridden in the child classes to do additional things.

When I open world composition and I’m using world shifting it tells me the new center location with X- Y- coordinates. What about Z-? What if I want to make game vertically huge? Is this Z also taken into account and not displayed to avoid further complications, or is ApplyWorldOffset just a 2D vector?
