SymmXMirror is a symmetry correction plugin for LightWave 3D.
There are still certain modeler tools that break symmetry or doesn’t respect the symmetry mode. That’s when this plugin comes in handy, quickly correcting those problems.
The idea of this plugin is based on Kevin MacPhail’s pmirror.p plugin released a few years back.
I used that plugin all the time, unfortunately it’s only available for 32-bit LightWave, when I made the switch to 64-bit, this was a missed gem for me.
So I wrote my own version, which should work on all current LightWave 3D platforms.
SymmXMirror automatically corrects symmetry errors in an object with a brutal technique. Basically the plugin selects the -X side of the mesh, flattens it, deletes it, mirrors the +X side and merges the points, which is a quick way to restore symmetry in an object if it gets broken.
I added an extra method that tries to intelligently find the center through the object if it or some points has moved away from the 0 position. This is pretty common for instance in situations where the object has been brought to ZBrush and back.
The tool is designed to be used in the initial stages of modeling when symmetry is wanted, when you get into the phase of adding vertex maps, UV maps and such this tool shouldn’t be used anymore as it might destroy some of those maps if they are unique on each side. For those occasion you might want to give my Fix Symmetry tool a spin.

I’m very interested in your contributions… What else deserves to be in this plugin? How can it be improved? Coders, feel free to fork the repository, make any updates and then send me a pull request. Non-coders, submit a request in the issue tracker.
There is no official support for this plugin, but if you run into any problems or bugs, you can file a report in the issue tracker and it will be looked into. You need to have a Google Account to file a new issue.
SymmXMirror has been tested on LightWave 3D 9.5 / 9.6, win32 and win64. As far as I know it should also work fine on the Mac.
