Setting Basic Brush Attributes

To quickly get started in Corel Painter, you specify basic brush attributes, such as brush size, opacity, and grain, on the property bar. Size determines the dimension of a single brush dab. You can also use the ghost brush to determine if a change in size is required. For information about the brush ghost, see Setting up the Drawing Cursor.

The ghost brush, the circle displayed to the left of the brushstroke, appears when a brush is selected and positioned over the canvas. It mirrors the size and shape of the brush dab.

Opacity controls the degree to which a stroke covers or builds up on the underlying pixels.

80% opacity (top) and 20% opacity (bottom).

Grain controls the interaction of color with the paper texture.

You can also set brush attributes, such as angle and squeeze, dynamically onscreen. A circle appears onscreen in the document window that lets you size and shape the brush within the context of the image.

The circle provides a visual representation of the brush size onscreen.

You can also access additional brush controls to further customize brushes. For example, you can set a minimum brushstroke size to control the tapering and widening of brushstrokes as stylus pressure or direction is varied. For more information, see Adjusting Brushes.

To set brush size Back to Top
1
 
In the toolbox, click the Brush tool .
2
 
Click the Brush Selector on the Brush Selector bar.
3
 
In the Brush Library panel, click a brush category, and click a brush variant.
4
 
On the property bar, adjust the Size slider , or type a value in the Size box.
If you want to scale the brushstroke feature proportionally with the brush size, click the Scale Feature With Brush Size button on the property bar.
Corel Painter may need to rebuild the brush after you resize it; therefore, you can expect a short delay.
You can also increase brush size incrementally by clicking the right square bracket ( ] ) key or decrease brush size by clicking the left square bracket ( [ ) key.
You can specify the default brush size increment value in pixels by choosing Corel Painter 12 Preferences (Mac OS) or Edit Preferences (Windows), clicking General in the Preferences list of categories, and typing a pixel value in the Brush Size Increment box.
You can also disable the scaling option in all areas by choosing Corel Painter 12 menu Preferences General (Mac OS) or Edit menu Preferences General (Windows), and enable the Disable Feature Scaling When Resizing Brush.
To set opacity Back to Top
1
 
In the toolbox, click the Brush tool .
2
 
Click the Brush Selector on the Brush Selector bar.
3
 
In the Brush Library panel, click a brush category, and click a brush variant.
4
 
On the property bar, adjust the Opacity slider , or type a percentage in the Opacity box.
When the Opacity setting is low, the applied color is thin, so you can see through to the underlying colors. When the setting is high, the applied color covers underlying pixels more completely.
Some methods and dab types do not allow you to adjust opacity.
When the Brush tool is active, you can set opacity by pressing a number key. Each number key is mapped to a fixed percentage. For example, 1 equals 10% opacity, 5 equals 50% opacity, and 0 equals 100% opacity.
To set grain Back to Top
1
 
In the toolbox, click the Brush tool .
2
 
Click the Brush Selector on the Brush Selector bar.
3
 
In the Brush Library panel, click a brush category, and click a brush variant.
4
 
On the property bar, adjust the Grain box slider, or type a percentage in the Grain box.
Adjust the slider to the left to reduce penetration and reveal more texture. Move it to the right to increase penetration and reveal less grain.
For liquid media brushes, Grain controls the amount of “pull.” For Image Hose brushes, Grain controls the mixture with the additional color. For other brushes, such as airbrushes, the Grain slider is not available.
To set brush attributes onscreen Back to Top

Change the brush opacity
Hold down Command + Option (Mac OS) or Ctrl + Alt (Windows) to display the Radius circle. While pressing the stylus, or holding down the left mouse button, press Command (Mac OS) or Ctrl (Windows), drag the Opacity circle in the image window until the circle is set to the opacity that you want, and then release the stylus or mouse button.
Change the brush squeeze setting
Hold down Command + Option (Mac OS) or Ctrl + Alt (Windows) to display the Radius circle. While pressing the stylus, or holding down the left mouse button, press Command (Mac OS) or Ctrl (Windows) twice, drag the Squeeze circle in the document window until the circle is set to the brush squeeze that you want, and then release the stylus or mouse button.
