Zip Merge is a Blender add-on designed to join complex geometry seams where standard distance-based merging creates unwanted overlaps. It is particularly useful for connecting clothing panels or other intricate mesh islands without collapsing adjacent vertices. The tool preserves existing UV layouts, avoiding the destructive workflow of bridging faces and dissolving edges. To use the add-on, users manually merge a few initial vertices, select a starting vertex, and execute the Zip Merge operator from the merge menu, adjusting the iteration count to complete the seam.
