Shockwave Effector
An expanding spherical wave front that pushes particles and repeats on a period.
The Shockwave Effector sends a ring of force outward from its position, again and again.
- Strength, Travel Speed, Wave Width, Repeat Period (s)
- Found in the node graph under Particles → Effectors
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. The default shockwave on a sphere emitter.
Inputs and outputs
| Port | Type | Purpose |
|---|---|---|
| Effectors In | Effector | The previous effector in the chain, if any. |
| Field Image | Texture | A texture read by the Image field shape. |
| Origin Object | Surface | A Null to parent the effector to. |
| Effectors Out | Effector | Wire it into the next effector, or into the Particle System's Effectors port. |
Parameters
- Strength (0–100, default 15).
- Travel Speed (0.1–50, default 6).
- Wave Width (0.05–10, default 0.8).
- Repeat Period (s) (0.2–30, default 3).
- Particle Use Amount (0–1, default 1) — the share of particles this effector acts on. Two effectors with the same amount act on different particles.
- Speed Variance (0–4, default 0) and Speed Bias (−1 to 1, default 0) — scatter the force per particle.
Field
- Field (default off) — limits the effector to a region. Field Shape (Sphere, Box, Plane, Image), Field Size (default 3), Falloff (default 0.5), Inner Radius, Invert Field, Field Follows Mouse, and Image Channel for the Image shape. The Field Position / Heading / Pitch / Roll / Scale block places it.
Every slider has a per-parameter animation bar, so it can be animated, audio driven, or MIDI mapped.
Examples
Beat pulse — drive Strength from a Sound modifier and set Repeat Period to the bar length.
Troubleshooting
Nothing moves. The effector's Effectors Out must reach the Particle System's Effectors port, directly or through the last effector in a chain.
