Wavefront object names missing from ModelIO submeshes

I have a wavefront model obj file with over 100 objects, each specified by a line in the file of form:

o object_name

Each of the objects appears as a submesh when imported with ModelIO. However, the

submesh name property is blank and not set to the name of the object as given in the

wavefront file. I can't find any other property that might contain the name.


How can I get the object name from the ModelIO data?


Thanks.
