Particles As Primitives
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 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.
