Face Sets¶

Face sets are another way to control the visibility state of the mesh in Sculpt Mode. They are designed to work in modes where brushes are the primary way of interaction and they provide much more control when working with meshes with complex shapes and overlapping surfaces. Geometry can be assigned to a face set and each face set is represented as a different color in the 3D Viewport. A pie menu to edit face sets can be accessed with W.

Face Set from Masked¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Face Set from Masked

Creates a new face set from Masked Geometry.

Face Set from Visible¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Face Set from Visible

Creates a new face set from all visible geometry.

Face Set from Edit Mode Selection¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Face Set from Edit Mode Selection

Creates a new face set corresponding to the Edit Mode face selection.

Init Face Sets¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Init Face Sets

Initializes all face sets on the mesh at once based off one of several mesh attribute properties.

Mode

The mesh data attribute used to define the boundaries for the face sets.

By Loose Parts: Creates a new face set per discontinuous part of the mesh.
By Materials: Creates a face set per Material Slot.
By Normals: Creates face sets for Faces that have similar Normals.
By UV Seams: Creates face sets using UV Seams as boundaries.
By Edge Creases: Creates face sets using Edge Creases as boundaries.
By Edge Bevel Weight: Creates face sets using Bevel Weights as boundaries.
By Sharp Edges: Creates face sets using Sharp Edges as boundaries.
By Face Maps: Creates a face set per Face Map.

Threshold

The minimum value to consider a certain attribute a boundary when creating the face sets.

Grow/Shrink Face Sets¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Grow/Shrink Face Sets
Tool: Edit Face Set
Hotkey: Ctrl-W, Ctrl-Alt-W

Expands or contracts the face set under the cursor by adding or removing surrounding faces.

Extract Face Set¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Grow/Shrink Face Sets

Creates a new mesh based on the selected face set. Once the operator is initiated, hover over the face set and LMB to create the new mesh. After the operator is finished the new mesh will be selected in Object Mode.

Invert Visible Face Sets¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Invert Visible Face Sets

Hides all geometry that is part of a face set and makes all hidden geometry that is part of a face set visible.

Show All Face Sets¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Show All Face Sets

Shows all hidden geometry that is part of a face set.

Randomize Colors¶

Reference

Mode: Sculpt Mode
Menu: Face Sets ‣ Randomize Colors

Generates a new set of random colors to render the face sets in the 3D Viewport.
