The Actor Portrait plugin allows you to display any actor as a 3D element in your UI! This is done by keeping a separete world where the actor is updated and rendered to a custom UI element.
This is abstracted away in C++, the only thing you need to do is drag the Actor Portrait UMG element into your designer, as you would with any other UI element.
