Zen Sets is an add-on for creating, managing, and visualizing Vertex Groups, Face Maps, and custom selection groups. It enables users to save selections of vertices, edges, faces, objects, and collections, displaying them with assigned colors directly in the 3D Viewport and UV Editor. The tool supports multi-object editing and allows conversion between native Blender groups and custom Zen Sets groups.

The add-on provides two primary selection modes: Sets Mode, where mesh elements can belong to multiple groups, and Parts Mode, where elements are restricted to a single group. Included operators can automatically generate groups based on parameters like materials, UVs, or seams. It also features utilities for creating objects from groups, setting sculpt masks, cleaning zero-weight vertex values, and batch renaming collections or vertex groups.
