Modifying raster brush settings

Settings inside the Edit dialog

The following settings are available:

General

• Size—sets the default width of the stroke. This can still be overwritten for individual brush strokes using the Width slider or the setting in the Stroke panel.
• Hardness—sets how hard the edges of the brush are. The brush appears softer as the percentage decreases.
• Flow—controls how fast colour is built up under your brush.
• Accumulation—sets the opacity or visibility of the brush.
• Spacing—sets the distance between each nozzle point. A lower percentage results in the nozzles blending together to give a flowing stroke. A higher percentage pushes nozzles away from each other creating a spray-style stroke.
• Rotation—sets the angle at which the brush nozzles are drawn. Great for non-round brushes, e.g. for calligraphic effects.
• Shape—sets the diameter of the brush nozzles.
• Blending Mode—changes how the applied colour interacts with existing colours on a layer. Select from the pop-up menu.
• Wet Edges—sets the default 'wet edge' behaviour of the brush. The 'wet edge' behaviour builds paint up along the edges of your pixel brush stroke, producing a watercolour effect.
• Custom Wet Edges—when enabled, you can apply a custom ramp (profile), which subtly changes how watery the stroke appears when the Wet Edges option in enabled.
• Associated Tool—sets the tool which is automatically selected when the brush is selected.

Dynamics

• These settings determine the extent to which a chosen controller (Pressure, Velocity, Rotation, etc.) will affect the above General settings. Pick a Controller from the pop-up menu and tap the adjacent Ramp profile icon to create your own custom profile using the ramp chart. Move circular nodes to reshape the non-linear ramp, add nodes to the ramp by tapping on the line, or select a node to remove it using the delete button. Enable the Linear button for straight lines between all nodes; If disabled (non-linear), nodes are connected using smooth curves.
• Scatter X—sets the deviation in the horizontal position of the stroke as it is painted.
• Scatter Y—sets the deviation in the vertical position of the stroke as it is painted.

Texture

For nozzle control:

• Brush Nozzles—displays the nozzles currently used in the current brush.
• Remove—deletes the selected nozzle from the preset.
• Add—adds an additional nozzle to the preset.
• Interpolate—when enabled, the quality of the brush tip is improved when affected by the currently set brush tip controller option.
• Nozzle-specific controller (Pressure, Velocity, Rotation, etc.)—changes how the nozzle interacts with additional nozzles used in the current brush. Select from the pop-up menu.
• Spline—displays the spline chart which can be shaped to adjust the nozzle's range.

For base texture control:

• Base Texture—displays the underlying texture or pattern for the current brush.
• Set Texture—launches a dialog to add a base texture, as an image, to the brush. For example, to simulate a textured surface like paper or canvas.
• Remove—deletes the base texture from the current brush.
• Invert—creates a negative version of the texture.
• Mode—controls how the base texture contributes to the current brush. Select from the pop-up menu.
  • None—the base texture is ignored, so only the brush nozzles are used.
  • Nozzle—allows nozzles to build up brush colour onto the base texture depending on flow and opacity response.
  • Final—the density of the base texture is kept constant, with no nozzle flow or opacity response.
• Scale—sets the size at which the texture is displayed. A lower percentage will display the texture at a larger size. A higher percentage will display the texture tiled at a smaller size.
