What it does

Saving a set

Select faces, edges or vertices in Edit Mode, press plus and type a name. The set takes the type of your select mode. With several objects in Edit Mode at once, one set name covers all of them.

Selecting a set again

Click the arrow next to a set to select it. Shift+click adds it to the selection, Ctrl+click removes it, Ctrl+Shift+click keeps only the overlap. A face set switches to face select mode, so it selects exactly its faces. Clicking a mesh set in Object Mode opens Edit Mode with the set selected.

The shelf popup

Shift+Alt+Q opens all sets under the mouse. The shortcut can be changed in the preferences.

Colours in Edit Mode

Every set has a colour. In Edit Mode the faces, edges and vertices of your sets are drawn in that colour, so you see at a glance what is saved. Each set can be shown or hidden in the overlay.

Hide and isolate

Hide a set, or isolate it to hide everything else. Reveal shows everything again without changing the selection.

Object sets

In Object Mode a set holds a group of objects. Select, hide and isolate work the same way.

Sets are mesh attributes

A mesh set is a Boolean attribute on the mesh, named set_ plus the set name. The data stays in your .blend file and travels with appended or linked meshes. Geometry Nodes read a set with a Named Attribute node. Without the extension, Select by Attribute still finds it.

Convert

Make face sets from materials, vertex sets from vertex groups, or write a set into a vertex group for modifiers such as Mask, Bevel or Solidify.

How it works

1. In Edit Mode select some faces and press plus in the Shelf tab of the sidebar. Name the set.
2. Save more parts the same way.
3. Click the arrow next to a set, or press Shift+Alt+Q and click its name, to select it again.

FAQ

Does undo work?

Yes. Undo after saving, changing or deleting a set restores the earlier state.

Do I need the extension to open files made with it?

No. The sets are normal mesh attributes.

Can I rename a set?

Yes, double-click it in the list. The attribute on every mesh is renamed with it.

Does it slow down Edit Mode on large meshes?

The colours are drawn up to a face limit you can set (200,000 by default) and are redrawn a moment after you stop moving vertices.

Does it send data anywhere?

No. No network access, no licence check.
