Hi, I'm making an cylindrical object in Blender with 12 corners. All edges are marked as Sharp. But when I put it into SteamVR Hammer and make it an editable Mesh (to texture e.g.) Hammer shows it as rounded object; the edges are all softed.

I think that from a certain angle, Hammer automatically rounds off an edge. Can this be prevented or the angle at which the rounding begins be changed?

The effect occurs with DMX export/import as well as with FBX
