Mirror Helper

This script is a simple mirror tool with a little added power where needed.  This will make it much easier to mirror multiple parts across a world or local space center plane, while automatically correcting the common normal and opposite errors.  It allows you to mirror groups of geometry, and mirror as instances.  It also allows you to mirror merge at angles.

To use:

1. Save either the Maya 2010 or Maya 2012 script to your documents\maya\*version*\prefs\scripts folder.
2. Start Maya.
3. In your command line or script editor, type the following and execute:

   MirrorHelper;


MIRROR SPACE
Choose between mirroring in world space or local space.

MIRROR UV
Check on to mirror the UVs of the mirrored geometry.  Works with Selection and Merge.

SELECTION
Mirrors multiple selections across desired plane.

INSTANCE
Mirrors multiple selections across desired plane as instances.

MERGE
Standard Maya mirrorMerge, but with some tweaks to work on multiple objects at once, and works with local space.

CUT
Standard Maya mirrorCut, but works on multiple objects.


Known issues
- Mirror Merge has a locked merge tolerance of .01.  This is editable as an input after the merge if the tolerance is undesirable.
- Mirror Merge requires center pivot to be moved to desired mirror point if mirroring in local space.
