Well, I worked out the OBJ format for my software 3DRelief (in the store by the way plug plug plug...:) and I can tell you straight you definately could create a full blown OBJ from just the v lines. In fact 3DRelief creates the v lines first and uses them to create everything else. Squished morphs are not safe, nore are morphs embedded in a cr2, hr2 etc if the contain/define the v lines
