Hiding & Masking

Reference

Mode:Sculpt Mode Menu:Sculpt

While sculpting, areas might be hidden behind parts of the mesh or they might be too close to other parts. To work through these, it is useful to isolate parts of a mesh to sculpt on. This can be done by either completely hiding parts of the mesh or by masking areas that can not be sculpted on.

Hide

Portions of the mesh can be hidden in Sculpt Mode to improve the viewport performance and to access parts of the mesh that would otherwise be difficult to access, because they are occluded by other parts.

The hidden faces cannot be sculpted on. Hiding is shared between Edit Mode and Sculpt Mode (i.e. hiding/unhiding in one mode affects the other mode too).

Show All Alt-H

Reveal all hidden parts.

Hide Bounding Box H

To hide a part of a mesh inside the selection. This works similar to Box Select tool.

Show Bounding Box Shift-H

To reveal a hidden part of a mesh inside the selection.

Hide Masked

Hides all masked vertices.

Mask

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

Black part is masked.

Brush

In order to edit the mask, select the Mask Brush from the Brush panel.

Editing

Masks can be edited across the entire model:

Invert Mask Ctrl-I

Inverts an existing mask.

Fill Mask

Fills the whole mask with a value of 1.

Clear Mask Alt-M

Fills the mask with a value of 0. To completely remove the mask data see Clearing Mask Data.

Box Mask 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 Shift-Ctrl-LMB

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

Совет

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.

Displaying

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.

Clearing 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.
