Emitter
Spawns particles inside a sphere, box, cylinder, torus, plane, disc, or point volume.
The Emitter node is the plain spawner. Pick a shape, a size, and a position, and the Particle System fills it with new particles.
- Seven Shape volumes
- Position X / Y / Z and an Origin Object port for parenting
- Found in the node graph under Particles → Emitters
The image on the right is the example patch itself. Drag and drop it onto the app, or load it with File → Load, to open the full graph. A default sphere emitter into a Particle System with a Point Renderer.
Inputs and outputs
| Port | Type | Purpose |
|---|---|---|
| Origin Object | Surface | A Null or other object to parent the emitter to. |
| Emitter | Emitter | Wire it into the Particle System's Emitter port. |
Parameters
- Shape — Sphere (default), Box, Cylinder, Torus, Plane, Disc, Point.
- Radius (0.1–30, default 1) — size of the volume.
- Position X / Y / Z (−20 to 20, default 0).
Every slider has a per-parameter animation bar, so it can be animated, audio driven, or MIDI mapped.
Examples
Rain sheet — Shape Plane, Radius 12, raised with Position Y 8, and a Gravity / Wind Effector.
Troubleshooting
Particles appear in a ball no matter the shape — the shape changes where particles are born; with no effector they stay near it. Add an effector to move them.
