Sorry for reactivating this old thread, but i have exactly the same problem. I try to export the Modern Street example with the one file par shape option. I got a file for every shape and every texture, but only one Material-File which has only two materials (Pavement_141, Curbs_123). (Same Problem with any other model)The export log:export started at: Tue Feb 25 18:16:30 2014
