I have bought many asset from here some work some dont but unless it states the person selling the asset its for unreal and has that file for uasset the fbx or obj files will not work for some reason or another unreal will not take some file. I bought one or two 3d model maps that had fbx or obj file unreal will not convert those to a map to be used so please take this with a grain of salt if you need model from here make sure it states that it is a uasset file or you will have headache trying to make it work.
