Options

Airbrush

If you hold the brush still, but are still pressing down, this will keep adding color onto the canvas. The lower the rate, the quicker the color gets added.

Mirror

This allows you to mirror the Brush tip with Sensors.

Horizontal

Mirrors the mask horizontally.

Vertical

Mirrors the mask vertically.

Some examples of mirroring and using it in combination with Rotation.

Rotation

This allows you to affect Angle of your brush tip with Sensors.

In the above example, several applications of the parameter.

1. Drawing Angle – A common one, usually used in combination with rake-type brushes. Especially effect because it does not rely on tablet-specific sensors. Sometimes, Tilt-Direction or Rotation is used to achieve a similar-more tablet focused effect, where with Tilt the 0° is at 12 o’clock, Drawing angle uses 3 o’clock as 0°.

2. Fuzzy – Also very common, this gives a nice bit of randomness for texture.

3. Distance – With careful editing of the Sensor curve, you can create nice patterns.

4. Fade – This slowly fades the rotation from one into another.

5. Pressure – An interesting one that can create an alternative looking line.

Lightness Strength

New in version 4.4: This allows you to affect the Lightness Strength of your brush tip with Sensors. Only available with brush tips in Lightness Map mode.

This changes the contrast of the brush tip, so that at 100%, the full effect of the lightness variation is visible in the brush, while at 0% the brush paints without any lightness variation. This allows a variable impasto effect with lightness brushes, and for variation in texture stamp brushes that use a lightness-enabled brush tip.

Scatter

This parameter allows you to set the random placing of a brush-dab. You can affect them with Sensors.

X

The scattering on the angle you are drawing from.

Y

The scattering, perpendicular to the drawing angle (has the most effect).

Sharpness

Puts a threshold filter over the brush mask. This can be used for brush like strokes, but it also makes for good pixel art brushes.

Strength

Controls the threshold, and can be controlled by the sensors below.

Soften Edge

Controls the extra non-fully opaque pixels. This adds a little softness to the stroke.

Changed in version 4.2: The sensors now control the threshold instead of the subpixel precision, softness slider was added.

Align the brush preview outline to the pixel grid.

Whether to have the brush outline align to the pixel grid. This is useful with some forms of pixel art.

New in version 5.1.

Size

This parameter is not the diameter itself, but rather the curve for how it’s affected.

So, if you want to lock the diameter of the brush, lock the Brush tip. Locking the size parameter will only lock this curve. Allowing this curve to be affected by the Sensors can be very useful to get the right kind of brush. For example, if you have trouble drawing fine lines, try to use a concave curve set to pressure. That way you’ll have to press hard for thick lines.

Also popular is setting the size to the sensor fuzzy or perspective, with the later in combination with a Perspective.

Softness

This allows you to affect Fade with Sensors.

Has a slight brush-decreasing effect, especially noticeable with soft-brush, and is overall more noticeable on large brushes.

Source

Picks the source-color for the brush-dab.

Plain Color

Current foreground color.

Gradient

Picks active gradient.

Uniform Random

Gives a random color to each brush dab.

Total Random

Random noise pattern is now painted.

Pattern

Uses active pattern, but alignment is different per stroke.

Locked Pattern

Locks the pattern to the brushdab.

Mix

Allows you to affect the mix of the Source color with Sensors. It will work with Plain Color and Gradient as source. If Plain Color is selected as source, it will mix between the currently selected foreground and background color. If Gradient is selected, it chooses a point on the gradient to use as painting color according to the sensors selected.

Uses

Flow map

The above example uses a Krita painted flowmap in the 3D program Blender. A brush was set to Source ‣ Gradient and Mix ‣ Drawing angle. The gradient in question contained the 360° for normal map colors. Flow maps are used in several Shaders, such as brushed metal, hair and certain river-shaders.

Gradient

Exactly the same as using Source ‣ Gradient with Mix, but only available for the Color Smudge Brush.

You can either:

• Leave the default Foreground ‣ Background gradient setting, and just change the foreground and background colors

• Select a more specific gradient

• Or make custom gradients.

Spacing

This allows you to affect Brush Tips with Sensors.

Isotropic spacing

Instead of the spacing being related to the ratio of the brush, it will be on diameter only.

Ratio

Allows you to change the ratio of the brush and bind it to parameters. This also works for predefined brushes.
