Hey. If you consider your UV work finished and simply want to move the islands to the left, do not use the Zen Unwrap operator. It generates a completely new unwrap based on the current selection, which means it isn't designed for simple relocation. Instead, just use a dedicated movement operator in the direction you need, such as this one: https://zenmastersteam.github.io/Zen-UV/latest/transform_sys/unified_transform_sys/#move Alternatively, you can use Move by Increment from the Advanced Transform panel: https://zenmastersteam.github.io/Zen-UV/latest/transform_sys/advanced_operators/#advanced-transforms Regarding **Zen Unwrap**: judging by your video, the operator generated a brand-new unwrap because all elements of the mesh were selected. As a result, it created new islands. One of these islands turned out to be exceedingly long, causing the rest of the islands to appear small since the new layout scales everything uniformly to maintain an identical Texel Density across all islands.
