Something I have been coming up against a lot. I delete half my model to work on it symmetrically, then create a mirror modifier to bring it back. But somehow while I’m working on it, it gets moved just enough that all the vertices that were along the center line get moved a tiny bit away from 0 on the Y axis so when I mirror it I get an annoying seam.
- How can I avoid this?
- How can I fix it once it has happened?
