Voronoi Fractal | Substance 3D Designer

Voronoi Fractal

In: Texture Generators /Noises

Intermediate

Description

The Voronoi Fractal node generates a fractal 3D Voronoi noise mapped to a 2D image using a Z-down orthographic projection.

This node can be tested with Cube GBuffers as input instead of an actual baked map (as seen in the Example Image below).

Alert:
This noise is meant to be used with the GPU engine only (i.e., Director OpenGL). Go to Tools > Switch engine... or press the F9 key to select the desired engine.

Parameters

  • Invert Boolean
    Inverts the output image.
  • Scale Float
    Controls the scale of the fractal Voronoi noise.
    Note: When Tiling is enabled on any axis, the scale adjustement is stepped. This is expected.
  • Size Float3
    Controls the size of the fractal Voronoi noise in the X, Y and Z axes. Non-uniform values result in a stretching or squashing effect.
    Note: When Tiling is enabled on any axis, the size adjustment is stepped. This is expected.
  • Offset Float3
    Applies an offset to the position of the fractal Voronoi noise in the X, Y and Z axes.
  • Disorder Float3
    The intensity of the random offset applied to each point of the noise in the X, Y and Z axes.
  • Distortion Intensity Float
    Controls the intensity of a warping effect applied on the fractal Voronoi noise.
  • Distortion Scale Multiplier Float
    Controls the scale of the deforming pattern used in the warping effect controlled by the Distortion Intensity.
  • Min Level Integer
    The minimum level of of repetition used in the fractal pattern. A wider minimum/maximum range results in a richer pattern with variation on more frequency ranges.
  • Max Level Integer
    The maximum level of of repetition used in the fractal pattern. A wider minimum/maximum range results in a richer pattern with variation on more frequency ranges.
  • Roughness Float
    Controls the balance between low and high levels of repetition in the fractal pattern.
    Note: A value of 0 results in an output which is not in line with other low values following it. This is expected.
    Note 2: This parameter is only available when the Blend Mode parameter is set to Add.
  • Lacunarity Float
    Controls how the applied fractal pattern fills space. A higher value results in less gaps in the pattern and a denser noise.
  • Global Opacity Float
    Controls the range of the fractal Perlin noise values from 0.
  • Rounded Curve Float
    Rounds the slope around each point of the noise to make it convex.
    Note: This parameter is not available when the Style parameter is set to Edge.
  • Distance Scale Float
    Adjusts the distance of the gradient around each point of the noise.
  • Distance Mode Integer
    Sets the method to compute the distance gradient around each point of the noise:
    - Euclidean
    - Manhattan
    - Chebyshev
    - Minkowski
  • Minkowski Number Float
    The order p of the Minkowski distance. If we divide the distance gradient into quadrants, this number impacts these quadrants as follows:
    - p is exactly 1: Straight
    - p is lower than 1: Concave
    - p is greater than 1: Convex
    Interesting values:
    - 1.0: Manhattan distance
    - 2.0: Euclidean distance
    - Infinity: Chebyshev distance
    Note: This parameter is only available when the Distance Mode parameter is set to Minkowski.
  • Blend Mode Integer
    Sets the method of blending together the values of overlapping cells in space:
    - Add: Add the values
    - Max: Retain the highest value
    - Min: Retain the lowest value
  • Style Integer
    Sets the method rendering the data of the fractal Voronoi noise, considering the noise is based on a set of points in space:
    - F1: the distance to the closest point in space
    - F2: the distance to the second closest point in space
    - F2-F1
    - F1*F2
    - F1/F2
    - Edge: the edge between each cell of the noise in space
    - Random color: assign a random flat color to each cell of the noise in space
  • Edge Thickness Float
    Adjusts the thickness of the edges detected between cells of the fractal Voronoi noise. Edges are detected in the X, Y and Z axes, thus some thicknesses may increase quicker than other depending on the cells' depth.
    Note: This parameter is only available when the Style parameter is set to Edge.
  • Random Color Seed Mode Integer
    Sets the method of acquiring the random seed for the color selection per cell:
    - Global Random Seed: Use the seed inherited by the node
    - Manual Seed: Use a discrete seed
    Note: This parameter is only available when the Style parameter is set to Random color.
  • Random Color Seed Integer
    The discrete random seed which should be used for the color selection per cell.
    Note: This parameter is only available when the Style parameter is set to Random color and the Random Color Seed Mode parameter is set to Manual Seed.
  • Enable Tiling Boolean
    Adjusts the fractal Voronoi noise so its resulting pattern repeats in the X, Y and Z axes.
