How to make a 2D menu that displays 3D elements

I’m wanting to make a UI screen somewhat like what super mario odyssey or pokemon sword/shield are accomplishing right now where they seem to have a 2D UI foreground, a 3D element and a 2D UI background
somewhat like this

where we have a 2D menu, a 3D element and a 2D background

I’m not asking for the logic of the menu or how to actually create the UI design, what I’m really asking is how can I have a 3D mesh, character or whatever mixed in with my widgets like that?

or maybe another approach is to ask, how can I impose a 3D element over a widget that is added to the screen?

I’ve thought of layering the elements, adding a foreground widget with all the menus, then a 3D mesh with a camera attached but then how would I add the background widget?

Render Targets

You create a nicely lit room for the 3d creature, add a camera and then render what the camera sees to a texture. Use the texture in a material displayed by an UMG element. That’s the gist.

Thanks for the help, render targets are actually what I was looking for
