How Do I Render A Dynamic Main Menu Through Orthographic Projections?

In this book I have called “Game Engine Architecture: Second Edition” by Jason Gregory (lead programmer at Naughty Dog Inc.), the author states that 3-dimensional overlays such as a dynamic main menu is often rendered using orthographic projections or via a projection via the regular perspective of a camera system, with the geometry positioned in view which the camera follows around.

How exactly can I do this? Does this require 3rd party software/scripting, or is all the built-in functionality in UE4? I really would like to have a dynamic main menu that is fully scriptable/programmable but I dunno exactly how to implement it.
