Download UV Scatter Script 1.4
Last Updated 24 March 2013
This plugin requires the pyQT python libraries to be added to your maya installation. They can be downloaded here for windows
and here for mac
I have only tested this plugin with maya 2013 64bit for Windows and Mac OS (Mountain Lion), but it should work on other versions.
If you run into any issues on 2011/2012 drop a comment about it and I will try and add support.
