Oh, also you can control how objects with the same name are processed for mesh exports by the setting under Options > Import/Export > "Combine same named objects":



If that is on, then objects with the same name will be all generated into one single mesh object in the mesh file.

If that is off, then objects with the same name will become separate mesh objects in the mesh file.

So if you don't want them combined set "Combine same named objects" off.
