Cellular Noise

Method

This node generates a cellular noise pattern which is potentially infinite. It works by dividing the space in to cells and placing a point in each cell, which is expanded to a sphere. The placing of the points is randomised.

Attributes

Name Description
Distance Offset Offsets the distance field values, causing the generated distance field to expand of contract.
Cell Size Size of the generated cells.
Jitter How much the spheres are randomly moved from their original cell positions.
CSG Mode These options change how a this node combines with the rest of the procedural system. To find out more, see CSG Operation.
  • Replace, Replaces the previous procedural system.
  • Union, Adds the new procedural to the old procedural system.
  • Intersection, Interesects the new procedural with the old procedural.
  • Subtract, Subtracts the new procedural from the previous procedural system.
  • Blend, Blends between both procedurals – driven by the CSG Blend Weight.
  • Union Blend, A combination of Union and Blend – driven by the CSG Blend Weight.
  • Smooth Union, The new procedural is added to the old, and smoothing is applied to the outcome. Driven by the CSG Blend Weight.
  • Smooth Subtract, The new procedural is subtracted from the old, and smoothing is applied to the outcome. Driven by the CSG Blend Weight.
  • Offset, Adds one procedural ontop of the other another.
  • Custom Code, allows you to enter your own expression code.
CSG Blend Weight How much the new procedural blends with the old procedurals, depending on the CSG Blend Mode.
Material Colour Modify the colour for the procedural material.
