I have a minor mirroring issue that is driving me crazy. This part of the model accidentally got rotated. I straightened it out the best I could and snapped each vertex to the grid. I've done this many times before to fix a model before mirroring it. However despite the model being lined up correctly it won't mirror properly. It always gives me a big gap in the middle.



This is what happens if I mirror it no matter the setting.





This is how it SHOULD look.
