Spray Brush Engine¶
A brush that can spray particles around in its brush area.
Options¶
Brush Tips (Used as particle if spray shape is not active)
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
Focuses 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 Image shape.
Shape Dynamics¶
- Random Size
Randomizes the particle size between 1x1 px and the given size of the particle in brush-tip or spray shape.
- Fixed Rotation
Gives a fixed rotation to the particle to work from.
- Randomized Rotation
Randomizes the rotation.
- Follow Cursor Weight
How much the pressure affects the rotation of the particles. At 1.0 and high pressure it’ll seem as if the particles are exploding from the middle.
- Angle Weight
How much the spray area angle affects the particle angle.
Color Options¶
- Random HSV
Randomize the HSV with the strength of the sliders. The higher, the more the color will deviate from the foreground color, with the direction indicating clock or counter clockwise.
- Random Opacity
Randomizes 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 colors instead of the foreground color.
- Fill Background
Fills the area before drawing the particles with the background color.
- Mix with background color.
Gives the particle a random color between foreground/input/random HSV and the background color.
