I created a Blender add-on to help me speed up the process of UV mapping with the "ultimate trim" technique that was developed at Insomniac games, but this could be helpful for any trim sheet based UV mapping approach.

More info on the ultimate trim technique available here:

Feel free to send me a message with any feedback or ideas for improving the add-on.
