Download
Installation
Windows | Maya 2013
1) Open the zip file and copy the scripts (.mel) to this directory:
Documents/maya/2013/scripts/
2) Copy the icons (.bmp) to this directory:
Documents/maya/2013/prefs/icons/
3) Restart Maya or enter rehash
in the script editor.
Usage
Select uvs and enter this command in the script editor:
sdv_orientUvShells
TIP: The shell definition pass works faster if you select less uvs per shell. This is mainly an issue with very high uv counts (10k+). Ideally you only need to select one uv per shell.
