How do I import FNV objects into UE4

Sorry if this sounds incredibly simple and noobish but I am extremely new to UE4. The most I know how to do is load up heightmaps and create objects. Anyways i’m trying to create a sort of Fallout New Vegas remake (a lot of work I know) but I don’t know how to export items from fnv into UE4. I’m not just trying to move the objects tho I also wish to take these textures. Where do I even begin?
