Erik Spellerberg shares his UVDeluxe script for Autodesk Maya, a UV mapping toolset with UI and intergrated texture window. UV Deluxe is a collection of UV tools that Eric has put together finding some of these features missing in Maya. Some of them, like moving UV shells already exist in other scripts, however Eric wanted to make one toolbox to contain everything. Check out the freeware Maya script UVDeluxe here.
