For example, if your brush uses a distinct shape, you may want to include sufficient spacing to avoid printing one copy over another.
Spacing: Modifies the distance between “repeats” of the brush’s shape. Angle: Sets the rotation of the brush tip, which is only visible on non-circular brushes. 100 per cent is a perfect circle, while zero per cent is a flat line. Roundness: Adjusts how circular or oval the brush tip is. Changing the hardness value will not change the size of the brush: regardless of fuzziness, the diameter of the brush remains the same. With a hardness value of zero per cent, the edges will be fuzzy and indistinct, fading in opacity as towards the edges of the brush. With a hardness value of 100 per cent, the brush will have a defined, visible edge. Hardness: Softens and sharpens the brush’s edge. The size marks the diameter of the brush, from edge to edge, including softened or fuzzy pixels created by adjusting the hardness value. Brush size is measured in pixels by default. Size: Shrinks and enlarges the brush tip’s size. By default, this is also bound to the F5 key. To see all available settings, select the brush folder icon, or select Window > brush settings. Basic brushes can be customised with some basic settings, but not all of these settings can be accessed from the default drop-down for every brush.
