Emitter

Emitter

Master toggle for the Emitter group. Unchecked (default): no continuous spawn, only the initial water fill. Check to enable and unlock the emitter settings below.

Position

Position at centre
Position at upper-left corner

Point in the comp where particles spawn (circular region, default 50%, 20%). Keyframeable.

Size

Size at 1 (pinpoint)
Size at 200 (wide)

Radius of the spawn region in pixels (1 to 200, default 20). Larger = wider "spray".

Rate

Rate at 10 particles per second
Rate at 2000 particles per second

Particles per second (0 to 2000, default 50). High values + small size = fire-hose.

Force %

Force at 0% (spawn at rest)
Force at 2000% (jet stream)

Initial velocity of spawned particles (0 to 2000, default 200). 0 = particles start at rest; high values = particles shoot out. Keyframeable.

Direction

Direction at 0° (up)
Direction at 180° (down)

Angle of the emission cone. 0° = up, 90° = right, 180° = down, 270° = left (default 180°). Keyframeable.

Spread %

Spread at 0% (laser-thin beam)
Spread at 100% (omnidirectional)

Angular width of the emission cone (0 to 100%, default 30%). 0% = laser-thin stream, 100% = omnidirectional.

Inherit Velocity %

Inherit Velocity at 0%
Inherit Velocity at 200%

Newly spawned particles inherit the emitter's or shape-layer's alpha content's motion (0 to 500, draggable to 200, default 0). At 100% they match the emitter's current velocity; above 100% overshoots stylistically.

Emitter Shape

Shape Mode: Outline
Shape Mode: Filled

Optional AE layer whose alpha defines where particles spawn. Shape Mode controls Outline (only along the alpha edge) or Filled (across the whole alpha area).

Link Position to Shape Layer

Link Position off
Link Position on

When on with an Emitter Shape assigned, binds Emitter Position to the shape layer's transform.position. For pixel / video layers with internal alpha motion, leave off: the plugin auto-detects and tracks content motion via a Kalman filter.
