PARTICLE Category

Nodes for controlling particle systems at runtime. Allow starting, stopping, and managing particle emitters in the scene.

Available Nodes

Node	Type	Description
Start Particles	Action	Activates a particle emitter
Stop Particles	Action	Deactivates a particle emitter
Spawn Particles	Action	Instances a particle emitter from the library
Set Particle Visible	Action	Shows, hides, or toggles emitter visibility

Notes

• Start Particles combines setVisible(True) with reinstancePhysicsMesh() to restart the simulation.
• Spawn Particles uses scene.addObject() — the emitter must exist in an inactive layer or the scene library.
• For one-shot effects (explosions, impacts), Spawn Particles with a short lifetime is the recommended pattern.
