Yes that's right. Moving individual vertices would of course be ideal, but it was a bit more than I was hoping for right now :-) What I'm talking about is gathering all the vertices in a group of objects and calculating the smoothing for all as if they were one. Then I can break the trailing wing tips into multiple objects, but not lose their edges. Basically I want to break the wing up but have the normals calculated as if it was whole.
