Ultimate Trim UV - Blender Add-on
Note: For a visual explanation of how this add-on works, check out the animated gifs on my Artstation project page: https://www.artstation.com/artwork/V5k34
-This add-on was written to speed up the process of UV mapping with the ultimate trim technique that was developed at Insomniac games, but could be useful for any trim sheet based UV mapping approach.
More info on the ultimate trim technique available here:

-This add-on will resize your rectangular UV islands to match the scale of a chosen trim index and align the island to the left, right, or center of the texture sheet.
-You can configure custom trim sheet sizes with 2 to 12 trim strips by choosing how many strips you need and inputting the vertical pixel height of each strip. Once configured you can save presets for these settings.
Includes a PDF for documentation on how to install and use the add-on as well as animated GIF images demonstrating setup/usage.
Supported Blender Versions: 2.79 - 3.0.0 or newer.
