The Oil Brush was designed to imitate painting with an oil brush and paints strokes with a relief. The density of the stroke varies across the entire line.
You can change the brush color using the Color panel, Swatches panel, Color Wheel panel, or by clicking the image with the Eyedropper tool. To pick a color sample, press and hold the I key and then click the image with the Eyedropper tool. After the hotkey is released, the painting tool becomes active again.
The basic tool settings are shown in the Tool Options panel above the Image Window. To display the full list of parameters, press the tool icon in the Tool Options panel, or right-click the image. To specify the parameter settings, enter a numerical value in the parameter’s field or use the slider.
Size (1-300). The maximum line width which can be obtained by the brush (in pixels).
Relief (0-100). The prominence of stroke details. As this parameter is increased, the pattern left by the brush’s hairs in the paint is more pronounced and the relief of strokes is stronger.
Paint Reserve (0-100). The length of painted lines. When the paint runs out, the brush stops painting on the surface and leaves a raised, faded stroke of paint.
Color Mixing check box. This defines the state of the paint in when applied by the brush. When this check box is activated, paint strokes will mix together as if the paint is wet. If the check box is deactivated, the paint will behave as if it is drying, and brush strokes will not mix together.
Flat Brush. The check-box changes the shape of the edges of the brush strokes. If it is enabled, the strokes look like drawn with a flat brush or a palette knife. When this option is disabled, the brush strokes look like created with a round brush or as if paint squeezed out of a tube.
Press the Default button to set all settings to their default values.
