This add-on accelerates the process of UV mapping using the ultimate trim technique originally developed at Insomniac Games, while remaining adaptable for general trim sheet workflows. It automatically resizes rectangular UV islands to match the exact scale of a chosen trim index and aligns them to the left, right, or center of the texture sheet.

Users can configure custom trim sheet dimensions containing between two and twelve trim strips by specifying the vertical pixel height for each strip. Once configured, these specific layout configurations can be saved as reusable presets to streamline future environment art and texturing tasks.
