Well if you used the symmetry modifier, juste delete half the mesh, and redo a symmetry. uv's will overlap. or If uv's are perfectly symmetrical, select half uv faces, break, mirror, and snap in uv vertex mode, with grid snap on.
Polygon Modeling --> Symmetry Tools --> (- to +) works for all vertex except the outer edges. Anyone know why? I reset xform on my model, but the symmetry tools refuse to symmetry the outer edges of my model. I tried setting the tolerance to like .1, but it still doesn't work. (Note: I can't use the symmetry modifier). I…
