I encounter the same problems I had in the Rhino3D-newsgroup. For some reason there are several explanations for using the "object"or "group" settings. In the obj. file. Some programs like Carrara or Poser use the "g" option for object representation, other use the "o" adjective. In Rhino3d 4.0 they  had an approved obj-im- and exporter that lets you choose if you wanted the "o" or the "g" adjective for objects. Unfortunately the importer still mess up the vertexorder, so you still can't use  it for morph editing. For the Rhino-addicts among us: there is still a freeware utility called OBJ23DM, with converts obj-files to Rhino's 3DM-files in a correct vertexorder, to use for morph editing.

Just my two-cents,

regards,

Bopper.
