Particles

Method

Generates a shape based on the positions and movement of particles from a particle system.

Example
Example Nodegraph

Attributes

Name Description
Particle Size Size of the generated particle shapes.
Blob Softness The softness of the blending between the blobs. Only functions with “Blobs” selected in Field Mode.
Size Randomness An amount of randomness applied to the size of each particle shape.
Error Distance Expands 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 Colours If 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 Mode Change 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 Mode These 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 Weight How much the new procedural blends with the old procedurals, depending on the CSG Blend Mode.
Affect Colour Toggles whether colour is used or not.
Always Enabled (No Time Bars) Always enabled regardless of node timeline.
Material Colour Modify the colour for the procedural material.
Custom CSG Code Allows for custom code to be used.
