Those lines actually disappear when Unimesh is activated without applying the subdivision depending on the model.

Hmm.  In Poser 12, I had lines at actor edges, when using any sort of bump mapping and subd if the figure was NOT set to unimesh.

From what I recall, the "unimesh" in Poser is a sort of hack to allow subd to work at all.  Not sure what they're doing but just giving it a quick thinking... it can't be easy :)
