Mask¶

Masking to control which areas of the mesh are influenced by sculpting.

Black part is masked.¶

Brush¶

To edit the mask, select the Mask Brush from the Brush panel.

Editing¶

Reference

Mode: Sculpt Mode
Menu: Mask

Masks can be edited across the entire model. Using A opens a pie menu to choose different operations.

Invert Mask¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Invert Mask
Hotkey: Ctrl-I

Inverts an existing mask.

Fill Mask¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Invert Mask

Fills the whole mask with a value of 1.

Clear Mask¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Invert Mask
Hotkey: Alt-M

Fills the mask with a value of 0. To completely remove the mask data, see Clear Sculpt-Mask Data.

Box Mask¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Box Mask
Hotkey: B

Works like the Box Select tool, it creates a rectangular mask region. Hold Shift to clear the mask of the selected region.

Lasso Mask¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Lasso Mask
Hotkey: Shift-Ctrl-LMB

Can be used to create a free-form mask, similar to the Lasso Select tool.

Порада

To clear the mask of areas with the Lasso Mask tool, first invert the mask, apply the Lasso Mask, and then invert the mask back.

Mask Filters¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Mask Filters

Mask filters are operations that are applied to the whole paint mask.

Type

Smooth/Sharpen Mask: Changes the crispness of the mask edge.
Grow/Shrink Mask: Changes the size of the mask.
Increase/Decrease Contrast: Changes the contrast of the mask.

Iterations

The number of times that the filter is going to be applied.

Auto Iteration Count

Use a automatic number of iterations based on the number of vertices of the sculpt.

Expand Mask by Topology¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Expand Mask by Topology
Hotkey: Shift-A

Creates a mask radiating outwards from the active vertex in a uniform manner.

Expand Mask by Curvature¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Expand Mask by Curvature
Hotkey: Shift-Alt-A

Creates a mask radiating outwards from the active vertex while following the curvature of the mesh.

Mask Extract¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Mask Extract

Creates a duplicate mesh object based on masked geometry.

Threshold: Minimum mask value to consider the vertex valid to extract a face from the original mesh.
Add Boundary Loop: Creates and extra boundary loop on the edges of the geometry, making it ready for adding a Subdivision Surface modifier later.
Smooth Iterations: Smooth iterations applied to the extracted mesh.
Project to Sculpt: Project the extracted mesh on to the original sculpt object.
Extract as Solid: Adds a Solidify Modifier to the newly created mesh object.

Mask Slice¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Mask Slice

Removes the masked vertices from the mesh.

Threshold: Minimum mask value to consider the vertex valid to extract a face from the original mesh.
Fill Holes: Fills concave holes with geometry that might have resulted from the Mask Slice operation.
Slice to New Object: Create a new object from the masked geometry.

Dirty Mask¶

Reference

Mode: Sculpt Mode
Menu: Mask ‣ Dirty Mask

Generates a mask based on the geometry cavity and pointiness.

Display Settings¶

Reference

Mode: Sculpt Mode
Popover: Viewport Overlays – Sculpt ‣ Mask

The mask display can be toggled as a viewport overlay. In the overlay popover, the opacity of the mask overlay can be adjusted to make it more or less visible on the mesh.

Clear Sculpt-Mask Data¶

Reference

Mode: Object/Edit Mode
Menu: Properties ‣ Object Data ‣ Geometry Data ‣ Clear Sculpt-Mask Data

Completely frees the mask data layer from the mesh. While not a huge benefit, this can speed-up sculpting if the mask is no longer being used.
