Scratches Generator (Normal)

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

• Spline Number: 1 - 512Amount of scratches (splines) to place.
• Max Segments Per Spline: 2 - 256Amount 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 - 1.0Uniform rotation of all splines, to orient them in a direction.
• Spline Rotation Random: 0.0 - 1.0Variation of angle, randomly rotates every spline.
• Spline Scale: 0.0 - 1.0Uniformly scales all splines.
• Spline Scale Random: 0.0 - 1.0Randomly scales each spline individually.
• Spline Distortion: 0.0 - 1.0Uniform distortion level across all splines.
• Spline Distortion Random: 0.0 - 1.0Randomises the level of distortion of each spline individually.
• Spline Distortion Frequency: 0.0 - 1.0Sets the frequency of distortion, controls the scale of distortion detail.
• Spline Width: 0.0 - 2.0Sets the width of all splines uniformly.
• Spline Width Random: 0.0 - 1.0Randomises the spline width of each spline individually.
• Spline Position Random: 0.0 - 1.0Randomises 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/TrueDetermines the units used for spline width settings.
• Luminance Random (Grayscale version only): 0.0 - 1.0Randomises the Luminance of each spline individually.
• Normal Intensity (Normal version only): 0.0 - 1.0Sets the strength of the Normal effect for every spline globally.
• **Normal Intensity Random **(Normal version only)****: 0.0 - 1.0Randomises 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 + EndSets whether and in what direction the splines fade.
• Fade Length: 0.0 - 1.0Sets the length of the fade effect, if enabled above.
• Non Square Expansion: False/True
  Enables compensation of squash and stretch with non-square ratios.
