## Brush¶

### Brush Type¶

Reference

Mode: Sculpt Mode
Panel: Tool Shelf ‣ Tools ‣ Brush
Blob
Pushes mesh outward or inward into a spherical shape with settings to control the amount of pinching at the edge of the sphere.
Clay C
Similar to the Draw brush, but includes settings to adjust the plane on which the brush acts.
Clay Strips
Similar to the Clay brush, but it uses a cube test to define the brush area of influence rather than a sphere.
Crease Shift-C
Creates sharp indents or ridges by pushing or pulling the mesh, while pinching the vertices together.
Fill/Deepen
Works like the Flatten brush, but only brings vertices below the brush plane upwards. The inverse of the Scrape brush is to Deepen by pushing vertices above the plane downward.
Flatten/Contrast Shift-T
The Flatten brush pulls the vertices towards the Sculpt plane. The inverse of the Flatten brush is the Contrast brush which pushes vertices up or down away from the Sculpt Plane.
Grab G
Used to drag a group of points around. Unlike the other brushes, Grab does not modify different points as the brush is dragged across the model. Instead, Grab selects a group of vertices on mousedown, and pulls them to follow the mouse. The effect is similar to moving a group of vertices in Edit Mode with proportional-editing enabled, except that Grab can make use of other Sculpt Mode options (like textures and symmetry).
Inflate/Deflate I
Similar to Draw, except that vertices in Inflate mode are displaced in the direction of their own normals.
Layer L

This brush is similar to Draw, except that the height of the displacement layer is capped. This creates the appearance of a solid layer being drawn. This brush does not draw on top of itself; a brush stroke intersects itself. Releasing the mouse button and starting a new stroke will reset the depth and paint on top of the previous stroke.

Mask M

Lets you select mesh parts to be unaffected by other brushes by painting vertex colors. The mask values are shown as grayscale. I.e the darker a masked area is, the less effect sculpting on it will have. See also the options of the Mask menu.

The mask brush has two modes:

Draw
Smooth Shift
Pressing Shift with the mask brush active will toggle the mask smoothing mode.
Nudge
Moves vertices in the direction of the brush stroke.
Pinch/Magnify P
Pulls vertices towards the center of the brush. The inverse setting is Magnify, in which vertices are pushed away from the center of the brush.
Rotate
Rotates vertices within the brush in the direction the cursor is moved. The initial drag direction is the zero angle and by rotating around the center you can create a vortex effect.
Scrape/Peaks
The Scrape brush works like the Flatten brush, but only brings vertices above the plane downwards. The inverse of the Scrape brush is to Peak by pushing vertices above the plane up away from the plane.
SculptDraw X
Moves vertices inward or outward, based the average normal of the vertices contained within the drawn brush stroke.
Smooth S
As the name suggests, eliminates irregularities in the area of the mesh within the brush’s influence by smoothing the positions of the vertices.
Snake Hook K

Pulls vertices along with the movement of the brush to create long, snake-like forms.

Pinch
Snake-hook tended to loose volume along the stroke, with pinch > 0.5 its possible to sculpt shapes without loosing volume
Rake
A factor to support grabbing the mesh with rotation following the cursors motion.
Thumb
Similar to the Nudge brush, this one flattens the mesh in the brush area, while moving it in the direction of the brush stroke.
Simplify
This brush collapses short edges (as defined by the detail size) whether or not the Collapse Short Edges option is enabled. This brush has no effect if dynamic topology is not enabled. It can be found in the Brush ‣ Sculpt Tool menu.

### Common Options¶

This option controls the radius of the brush, measured in pixels. F allows you to change the brush size interactively by dragging the mouse and then LMB (the texture of the brush should be visible inside the circle). Typing a number then enter while using F allows you to enter the size numerically. Brush size can be affected by enabling the pressure sensitivity icon, if you are using a Graphics Tablet.
Strength

Controls how much each application of the brush affects the model. For example, higher values cause the Draw brush to add depth to the model more quickly, and cause the Smooth brush to smooth the model more quickly. This setting is not available for Grab, Snake Hook, or Rotate.

You can change the brush strength interactively by pressing Shift-F in the 3D View and then moving the brush and then LMB. You can enter the size numerically also while in Shift-F sizing. Brush strength can be affected by enabling the pressure sensitivity icon, if a supported tablet is being used.

Tip

If the range of strengths does not seem to fit the model (for example, if even the lowest strength setting still makes too large of a change on the model) then you can scale the model (in Edit Mode, not Object Mode). Larger sizes will make the brush’s effect smaller, and vice versa.

Autosmooth
Sets the amount of smoothing to be applied to each stroke.
Normal Weight Ctrl

Constrains brush movement along the surface normal. Especially useful with the Grab Brush, can be temporarily enabled by holding Ctrl. e.g. Grab brush can be used to push a depression (hole) into the mesh when Normal Weight is set.

Applies to Grab and Snake Hook brushes.

ToDo.
Sculpt Plane

Use this menu to set the plane in which the sculpting takes place.

Area Plane
The plane is located at the average height above/below the vertices within the brush area. Essentially, this means that the direction is dependent on the surface beneath the brush.
View Plane
ToDo.
X, Y, Z Plane

Global.

ToDo.

Plane Offset
ToDo.
Trim
ToDo.
Front Faces Only
When enabled, the brush only affects vertices that are facing the viewer.
Add/Subtract Ctrl
Brush direction toggle. Ctrl pressed while sculpting.
Accumulate
Causes stroke dabs to accumulate on top of each other.
