Hotkey

Shift-Ctrl-LMB

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.

Mask ‣ Expand Mask by Topology

Hotkey

Shift-A

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

Sculpt Mode

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

Mode

Sculpt Mode

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.

Create a new object from the masked geometry.
