UV Shell Symmetry

This tool allows you to enforce symmetry on UV shells that are topologically symmetrical.

Usage Instructions:

1. Selection: Select a singular center edge that defines the topological center of a UV shell. The script will work even if the rest of the model is asymmetrical.
2. Symmetry Options:
   • You can choose to mirror UVs from left to right, top to bottom, or in the opposite directions.
   • Alternatively, you can average the positions of the two sides by enabling "Average Symmetry".
3. Axis Determination:
   • If the selected edge is mostly vertical, the mirror will happen across the U-axis.
   • If the edge is mostly horizontal, the mirror will happen across the V-axis.

Installation and Execution:

1. Place uv_shell_symmetry.py in your Maya Scripts Directory.
2. Run the following command from a Python tab in the Maya Script Editor:

import uv_shell_symmetry

uv_shell_symmetry.UI.show_UI()
