Scratches Generator


Scratches Generator (Normal)

In: Generators/Patterns

Complex

Description

This places random scratches with a lot of customisation options, for example allowing you to set direction, spread and distortion.

There's a special version of Scratches Generator, Scratches Generator Normal, which generates Normalmaps based on the depth of these scratches. Most options are exactly the same, but it has a few extra parameters clearly marked for Normal settings (see below).

Parameters

 Click here to expand parameters...
  • Spline Number: 1 - 512
    Amount of scratches (splines) to place.
  • Max Segments Per Spline: 2 - 256
    Amount of segments/subdivisions over the length of a scratch. Leads to smoother curves and distortions. The effect is more noticeable with higher Distortion values.
  • Spline Rotation: 0.0 - 1.0
    Uniform rotation of all splines, to orient them in a direction.
  • Spline Rotation Random: 0.0 - 1.0
    Variation of angle, randomly rotates every spline.
  • Spline Scale: 0.0 - 1.0
    Uniformly scales all splines.
  • Spline Scale Random: 0.0 - 1.0
    Randomly scales each spline individually.
  • Spline Distortion: 0.0 - 1.0
    Uniform distortion level across all splines.
  • Spline Distortion Random: 0.0 - 1.0
    Randomises the level of distortion of each spline individually.
  • Spline Distortion Frequency: 0.0 - 1.0
    Sets the frequency of distortion, controls the scale of distortion detail.
  • Spline Width: 0.0 - 2.0
    Sets the width of all splines uniformly.
  • Spline Width Random: 0.0 - 1.0
    Randomises the spline width of each spline individually.
  • Spline Position Random: 0.0 - 1.0
    Randomises the position of each spline individually. The lower this value, the more splines will cluster to the center of the canvas. Can be used to create spots of scratches.
  • Set Spline Width in px: False/True
    Determines the units used for spline width settings.
  • Luminance Random (Grayscale version only): 0.0 - 1.0
    Randomises the Luminance of each spline individually.
  • Normal Intensity (Normal version only): 0.0 - 1.0
    Sets the strength of the Normal effect for every spline globally.
  • Normal Intensity Random (Normal version only): 0.0 - 1.0
    Randomises the normal strength for each spline individually.
  • Normal Format (Normal version only): DirectX, OpenGL
    Switches between different Normalmap formats (inverts the green channel).
  • Fade Mode: None, Start, End, Start + End
    Sets whether and in what direction the splines fade.
  • Fade Length: 0.0 - 1.0
    Sets the length of the fade effect, if enabled above.
  • Non Square Expansion: False/True
    Enables compensation of squash and stretch with non-square ratios.
