The Dynamics operator makes every clone above it a rigid body in the comp's physics world. Gravity, walls, forces and other bodies are shared by the whole comp and set in Dynamics World.
How to use it
- Make clones: a Cloner, Grid, text, or Fracture on a single shape.
- Choose Geo Ops ▸ Dynamics ▸ Dynamics.
- Play. Click empty space to deselect and adjust gravity and walls under Dynamics World.
Parameters
| Name | What it does | Default/range |
|---|---|---|
| Type | Dynamic: every clone falls and collides. Dormant: asleep until something hits it. Static: fixed colliders. | Dynamic |
| Collider | Outline: each clone's own shape (a letter's). Hull: its convex outline, cheaper. Box / Circle: its bounds. | Outline |
| Density | Mass per area. | 1, min 0.001 |
| Friction | How much clones grip when sliding. | 0.5, min 0 |
| Bounce | How much they rebound. | 0.2, 0–1 |
| Damping | Slows movement over time. | 0, min 0 |
| Spin Damping | Slows spinning over time. | 0.05, min 0 |
| Velocity X / Y | Starting speed. | 0, 0 px/s |
| Spin | Starting spin. | 0 °/s |
| Random | Varies the starting values per clone. | 0, 0–1 |
| Seed | Which random pattern. | random at add time |
| Stagger | Holds clone i still for i × Stagger before it drops. | 0 s, min 0 |
Tips
- Use Bake to Keyframes in Dynamics World to freeze a simulation.
- To make a whole layer a body instead of its clones, use Make Rigid Body.
