i made a simple barrel to try my un wrapping skills. i selected cylindrical unwrapping thinking that would be a logical choice. the body of the barrel went ok but the top and bottom of the barrel got exported as a flat face on it's side so it's an edge and not a face if that makes sense. i clicked the face top and bottom of the barrel and that long edge showed up in my uv editor in maya. i don't know but i think maya flipped the face on it's side and that's why it looks like an edge.

what gives?
