Editing Brush Attributes

You can perform many useful edits to your brushes, in addition to resizing them. Use the Brush controls to edit brush parameters.

To edit brush attributes:

1. Select the brush from the palette.
2. Change the attributes in the Brush controls.

Changing Brush Shape

You can use either an elliptical or a rectangular brush. To change the brush shape, select a shape from the Shape list.

Changing Aspect Ratio

To change the aspect ratio, move the Aspect slider from left to right to increase the vertical dimension with respect to the horizontal. This applies to both elliptical and rectangular brushes.

Changing Contact Angle

To change the contact angle of the brush, move the Angle slider from left to right. This rotates the contact angle counter-clockwise.

Changing Spacing

The amount of space between dabs of paint depends on the diameter of the brush used to create the dab and the spacing number. The spacing number is the percentage of the diameter of the brush used between the leading edges of two brush dabs.

The following example shows different brush spacing settings. In the first line, several dabs are shown touching, but not intersecting. The spacing value is 100%. In the second line, several dabs of the same brush intersect; the space between their leading edges is half the diameter of the brush. The spacing value is 50%. The last line shows no space between the dabs of paint in the stroke. Its spacing value is zero.

To change the amount of space between dabs of paint, move the Spacing slider. The higher the number, the more space appears between dabs.

Changing Brush Type

Enable Airbrush to create an airbrush stroke using a normal brush. Use the Flow slider to adjust the amount of color that is applied with the airbrush. The higher the number on the slider, the greater the density of color.

Anti-Aliasing

Enable Anti-Alias to prevent jagged edges on brush strokes.

Transform with Object

Enable Transform with Object to scale, shear, or rotate the brush stroke of a paint object in proportion to the object.

Adjusting the Opacity of a Brush Stroke

Use the profile graph to control the opacity profile of the brush.

When adjusting the opacity profile, you can access the following controls.

Click:	To:
Profile curve	Add a control point.
Line type button	Toggle between linear and Bezier profiles. A Bezier graph creates a profile where the opacity changes more gradually.
Vertical flip button	Invert the profile vertically.
Horizontal flip button	Invert the profile horizontally.
Remove Control Point button	Remove the selected control point.
Reset button	Remove all control points to create 100% opacity across the entire brush.

Moving the Brush Handle

When you draw in the active viewport, the cursor drags the brush handle. By default, the cursor corresponds to the center of the brush. Use the Handle button to move the brush handle. You can place the handle anywhere, even outside the brush. To move the handle back to the center of the brush, click the Center button.
