Hi Micha, just a note on object names.

For the next beta I've added an option to control whether to combine meshes for objects of the same name or not, it will be under
Options > Import/Export > Combine same named objects.

However, Rhino's OBJ importer seems to automatically combine objects with the same name even if they are listed as separate objects. Probably you can repeat this in Rhino, do something like make 3 boxes with all the same name, export to OBJ and read it back in again.

So probably you've had this combining behavior for a while without really knowing about it anyway.

But that export batch script will not have this issue since part of that script puts a unique name on every object.
