Pixel brush settings can be modified before you paint on your design. Basic modifications can be made directly on the context toolbar, while advanced settings can be accessed from the context toolbar's More button. You can edit the brush in the Brushes Studio itself, but this edits your brush permanently unless you duplicate it.
Settings via More button
The following settings are available:
General
Size—sets the default width of the stroke. This can still be overwritten for individual brush strokes using Width on the context toolbar or the Stroke Studio.
Hardness—how hard the edges of the brush are. The brush appears softer as the percentage decreases.
Flow—controls how fast color 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 color interacts with existing colors on a layer. Select from the pop-up menu.
Wet Edges—sets the default 'wet edge' behavior of the brush. The 'wet edge' behavior builds paint up along the edges of your pixel brush stroke, producing a watercolor effect.
Custom Wet Edges—When enabled, you can apply a custom ramp (profile), which subtly changes how watery the stroke appears when Wet Edges in enabled.
Dynamics
Jitter 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 the preset will allow as a stroke is painted.
Scatter Y—sets the deviation in the vertical position of the stroke the preset will allow as a stroke is painted.
Texture
For nozzle control:
Brush Nozzles—displays the nozzles currently used in the current brush.
Add—adds an additional nozzle to the preset.
Remove—deletes the selected nozzle from the preset.
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 color 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.
To modify pixel brush settings:
Choose one of the following:
With the Paint Brush Tool selected, on the context toolbar, adjust Width, Opacity, Flow, etc.
With the Paint Brush Tool selected, on the context toolbar, tap More to access more advanced settings, adjust settings, then tap OK.
To reset context toolbar brush settings back to brush defaults:
On the Brushes Studio, long press a chosen brush and tap Reset from the pop-up menu.
