Generate shapes from particles for a procedural.



Method #

This node generates a distance field using the positions of particles from a particle system.

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.

Particle SizeSize of the generated particle shapes.
Blob SoftnessThe softness of the blending between the blobs. only functions with “blobs” selected in field mode.
Size RandomnessAn amount of randomness applied to the size of each particle shape.
Error DistanceExpands the allowable values for generating the Distance Field. Higher values often get rid of jagged edges and odd rendering behaviours, but with decreased performance.
Use Particle ColoursIf this is enabled then the colour of each primitive will be taken from it’s particle. This only has an effect for procedural renderers that support colour generation (and which have
Field ModeChange how the emitted particles generate in the procedural system.
  • Spheres : Each particle is generated as a simple sphere.
  • Blobs : Each particle is generated as a blob which smoothly blends and combines with other blobs in the scene.
CSG ModeThese options change how 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.
Affect ColourToggles whether colour is used or not.
Always Enabled (No Time Bars)Always enabled regardless of node timeline.
Material ColourModify the colour for the procedural material.
Custom CSG CodeAllows for custom code to be used.
