Particles As Primitives
Updated: 22 Mar 2024
Generate primitive shapes from particles for a procedural.
Particles As Primitives
Method #
This node generates primitives based on the positions of particles from a particle system.
Nodes connected to this node will generally follow the parent child hierarchy. Other Procedural Generator nodes can be configured to combine with this shape using their CSG modes, and displacement nodes will only apply to this shape.
Parameters
These properties control the core behaviours of the node.
Parameter Details Particle Size Edit the size of the particles
Potential Cutoff Controls the blending range of every particle (how smoothly they are blended).
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.
Primitive Type Change the shape of the generated primitives.
CSG Mode These options change how a this procedural node combines with the existing of the procedural system.
- Replace : Replaces the previous procedural system with a new procedural shape.
- Union : Simply combines both the new procedural shape and the existing procedural system.
- Intersection : Interesects the new shape with the shape before.
- Subtract : Subtracts the new procedural shape from the existing procedural system.
- Blend : Blends between both the new procedural shape and the existing procedural system, driven by the CSG Blend Weight.
- Union Blend : A combination of union and blend which tries to preserve both objects more, with the blending being driven by the CSG Blend Weight.
- Smooth Union : The new procedural is added to the old, and smoothing (driven by the CSG Blend Weight) is applied to the outcome.
- Smooth Subtract : The new procedural shape is subtracted from the existing procedural system, and smoothing (driven by the CSG Blend Weight) is applied to the outcome.
- Offset : Blends one procedural ontop of the other another withing the area of the original procedural system.
- 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 Weight.
Material Colour Modify the colour for the procedural material.
