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

Mode

Sculpt Mode

Menu

Face Sets ‣ Face Set from Masked

Creates a new face set from Masked Geometry.

Face Set from Visible

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

Sculpt Mode

Menu

Face Sets ‣ Face Set from Edit Mode Selection

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

Initialize Face Sets

Sculpt Mode

Menu

Face Sets ‣ Initialize 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 Face Set Boundary

Creates a face set for each isolated face set. This mode is useful for splitting the patterns created by Expand Face Set by Topology into individual Face Sets for further editing.

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

Mode

Sculpt Mode

Menu

Face Sets ‣ Grow/Shrink Face Sets

Tool

Edit Face Set

Shortcut

Ctrl-W, Ctrl-Alt-W

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

Expand Face Set by Topology

Reference

Mode

Sculpt Mode

Menu

Face Sets ‣ Expand Face Set by Topology

Shortcut

Shift-W

Creates a face set radiating outwards from the active vertex in a uniform manner. This operator uses the same internal operator as Expand Mask by Topology meaning all the hotkeys and functionality works the same as that tool.

Muista

This operator is meant to be used interactively through the shortcut.

Expand Active Face Set

Reference

Mode

Sculpt Mode

Menu

Face Sets ‣ Expand Face Set by Topology

Shortcut

Shift-Alt-W

Expands a face set by radiating outwards from the face set in a uniform manner. This operator uses the same internal operator as Expand Mask by Topology meaning all the hotkeys and functionality works the same as that tool.

Muista

This operator is meant to be used interactively through the shortcut.

Extract Face Set

Reference

Mode

Sculpt Mode

Menu

Face Sets ‣ Extract Face Set

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

Sculpt Mode

Menu

Face Sets ‣ Show All Face Sets

Shortcut

Alt-H

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

Randomize Colors

Mode

Sculpt Mode

Menu

Face Sets ‣ Randomize Colors

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