Paint properties

General

Color

Displays the current color for the Paint Brush. Clicking the color box displays the Paint Tool Color window which lets you modify the color assigned to the Paint Brush color.

Size

Sets the radius of the tool. Size is measured in world space units (for example, by default a Size of 100 = a radius of 100 centimeters). Hotkeys: press b + left-mouse-button and drag the mouse, or use [ (to reduce size) ] (to increase size).

Strength

Determines how much the sculpt tool affects the surface. Depending on the tool, this property is represented either as a percentage of the maximum power available or as a height expressed in world space units. Hotkeys: press m + left-mouse-button and drag the stylus/mouse, or use ; (to reduce strength) ' (to increase strength).

Mirror

Reflects a stroke from one side of a model to the other, along the specified axis:

Off - strokes are not reflected.
X - strokes are reflected across the world space X axis.
Y - strokes are reflected across the world space Y axis.
Z - strokes are reflected across the world space Z axis.
Local X - strokes are reflected across the local space X axis.
Local Y - strokes are reflected across the local space Y axis.
Local Z - strokes are reflected across the local space Z axis.
Tangent - strokes are reflected across the topological center line of a topologically symmetrical model. To use tangent space mirroring on a model, you must first identify the model's topological center by selecting two faces that straddle the center line and then selecting Edit > Set Topological Center. For models with n-sided faces this procedure needs to be repeated on level1.

Use Stamp Image

Turns on the selected stamp for the tool. Stamps modify the strength of the sculpt brush according to the gray scale values in the stamp image. The darker the overall values the lower the strength of the tool. Not all sculpt brushes work with Stamps.

Orient To Stroke

Orients the stamp such that its top points along the direction of the stroke.

Rotate

Rotates the stamp image clockwise.

Horizontal Flip

Flips the stamp image horizontally.

Vertical Flip

Flips the stamp image vertically.

Randomize

Turns on the randomize features for the tool stamp.

Random Horizontal Offset

Randomizes the horizontal position of the brush tip dynamically through the stroke.

Random Vertical Offset

Randomizes the vertical position of the brush tip dynamically through the stroke.

Randomize Rotate

Randomizes the rotation of the brush tip dynamically through the stroke.

Randomize Scale

Randomizes the size of the brush tip dynamically through the stroke.

Randomize Strength

Randomizes the strength of the brush tip dynamically through the stroke.

Horizontal Flips

Randomly flips the position of the brush tip along its X axis dynamically through the stroke.

Vertical Flips

Randomly flips the position of the brush tip along its Y axis dynamically through the stroke.

Stamp Spacing

Controls the stroke’s stamp frequency/continuity when using a sculpt or paint tool. Depending on the Size and Falloff settings for a tool, the Stamp Spacing can be set to a higher value to refine the tools behavior and improve the appearance of the resulting stroke. The default setting is 0 and ranges between 0 and 100. The higher the setting, the more visible gaps occur on the stroke depending on the tool settings.

Steady Stroke

An option that helps to produce a smoother tool stroke by filtering mouse/stylus movements. When Steady Stroke is turned on a vector displays on the tool cursor and the stroke is not drawn on the model until the mouse/stylus has moved a distance equal to the length of the vector. The length of the vector is controlled by the Steady Stroke Distance property.

Steady Stroke Distance

Sets the length of the Steady Stroke vector on the tool cursor. This distance limits when the stroke will be drawn when the stroke is made on the model.

Falloff

Falloff

Specifies how the sculpt tool has a diminishing effect (or not) from its center point to its outer edge. The falloff is represented as a curve that can be edited.

Falloff presets are available in the Falloff tool tray.

The following options describe items that appear when you right click in the falloff image within the Properties window:

Insert Point - inserts a new point under the cursor.
Select Point - selects the point under the cursor (when the cursor is hovering over a point).
Delete Point - deletes the point under the cursor (when the cursor is hovering over a point).

Snap

Constrains points to the grid.

Store To

Save the current falloff curve to the tray.

Advanced

Remember Size: Preserves the size of the brush between usage. With Remember Size off, the brush will inherit the size of the brush used before it.
Orient To Surface: Orients the tool ring display (in the 3D View) along the normal of the face under the center of the ring. Orient To Surface does not influence the effect of the brush on the surface -- only the display of the cursor.

Pen Pressure

Min Size: Specifies how small the tool size is when the lightest pressure is applied to the pen. Min Size is expressed as a percentage of the primary tool’s Size property. For example, a Min Size of 100 indicates there is no size variance, regardless of the pressure applied.
Min Strength: Specifies how weak the tool strength is when the lightest pressure is applied to the pen. Min Strength is expressed as a percentage of the primary tool Strength. For example, a Min Strength of 100 indicates there is no strength variance, regardless of the pressure applied.
