[Help] Get the 3d mesh from a full map?

[ZidSliver]

Good afternoon, I have a query for the CUSTOMER SIDE Developers or experts on the subject, I would like to know if some way to Rip or get a maya3d is already OBJ / FBX of any specific map, by that I mean to have all the objects in a only 3D file to be able to use it in my development.PSD: I know it is possible because they already did it with a certain amount of Lorencia, which helped me to remake it in the UE4.
