Hi um, it says that the map exports with the objects now or something -cant remember exactly what it said- so um for Example. if you had a object that no one else had, you know like a custom made one, if you put that in a new map and then exported it, when other people download the map will the object also be downloaded with it? so they can actuarlly see it? (because in the old version i knew that if you didnt have the object you couldnt see it.) please reply? thanks.
