A brush that can spray particles around in it's brush area.

Reference

Parameters

Spray Area

The area in which the particles are sprayed.

Diameter
The size of the area.
Aspect Ratio
It's aspect ratio: 1.0 is fully circular.
Angle
The angle of the spray size: works nice with aspect ratios other than 1.0.
Scale
Scales the diameter up.
Spacing
Increases the spacing of the diameter's spray.

Particles

Count
Use a specified amount of particles.
Density
Use a % amount of particles.
Jitter Movement
Jitters the spray area around for extra randomness.
Gaussian Distribution
Focusses the particles to paint in the center instead of evenly random over the spray area.

Spray Shape

If activated, this will generate a special particle. If not, the brush-tip will be the particle.

Shape
Can be...
  • Ellipse
  • Rectangle
  • Anti-aliased Pixel
  • Pixel
  • Image
Width & Height
Decides the width and height of the particle.
Proportional
Locks Width & Height to be the same.
Texture
Allows you to pick an image for the <menu choice>image</menuchoice> shape.

Shape Dynamics

Random Size
Randomises the particle size between 1x1 px and the given size of the particle in brush-tip or sprayshape.
Fixed Rotation
Gives a fixed rotation to the particle to work from.
Randomised Rotation
Randomises the rotation.
Follow Cursor Weight
How much the pressure affects the rotation of the particles. At 1.0 and high pressure it'll seem asif the particles are exploding from the middle.
Angle Weight
How much the spray area angle affects the particle angle.

Color Options

Random HSV
Randomise the HSV with the strength of the sliders. The higher, the more the color will deviate from the foreground colour, with the direction indicating clock or counter clockwise.
Random Opacity
Randomises the opacity.
Color Per Particle
Has the color options be per particle instead of area.
Sample Input Layer.
Will use the underlying layer as reference for the colours instead of the foreground colour.
Fill Background
Fills the area before drawing the particles with the background color.
Mix with background color.
Gives the particle a random colour between foreground/input/random HSV and the background color.
