In this video, I did the following: 1. Since your islands were too large, I didn't spend time tweaking their current UV layout. It was simpler to run Unwrap right away and work with normalized islands. 2. After unwrapping, the islands reflected the actual mesh geometry. To align them cleanly with the texture, we needed to turn them into a clean grid, so I used the Quadrify operator. 3. Next, I used World Orient to keep the texture direction consistent across all polygons, matching the natural flow of dripping grime. 4. To ensure every island has the same height and stretches the texture completely from top to bottom, I applied the Fit operator. Now all islands are aligned vertically and snapped to the left edge of the texture space. 5. Optionally, I used the Touch Tool to fine-tune the island alignment so the texture blends more naturally to my eye.
