Cellular Noise

Cellular Noise

Generates a cellular noise pattern for a procedural.



Method #

This node generates an infinite cellular noise pattern. It works by dividing the space in to cells and placing a point in each cell, which is expanded to a sphere. the points are then randomly ofset to form the cellular noise.

Nodes connected to this node will generally follow the parent child heirarchy. Other Procedural Generator nodes can be configured to combine with this shape using thier CSG modes, and displacement nodes will only apply to this shape.


These properties control the core behaviours of the node.

Distance OffsetOffsets the distance field values, causing the generated distance field to expand of contract.
Cell SizeSize of the generated cells.
JitterHow much the spheres are randomly moved from their original cell positions.
CSG ModeThese 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 WeightHow much the new procedural blends with the old procedurals, depending on the CSG Blend Mode.
