## Limiter operator

The Limiter operator can be used to constrain various particle properties.

#### Position

• Limit position: controls whether the position values of particles will be clamped.

• X/Y/Z: sets the min/max allowable values.

• Variation %: the per-particle percentage of variation to apply.
• Use shape bounds: considers the bounding box of the particle shape when clamping its position.

• Affect velocity: controls whether velocity values are cleared for particles whose position is limited.

#### Scale

• Limit scale: controls whether the scale values of particles will be clamped.

• X/Y/Z: sets the min/max allowable values.

• Magnitude min/max: sets the minimum/maximum overall magnitude of particle scale vectors.

• Variation %: the per-particle percentage of variation to apply.

#### Velocity

• Limit velocity: controls whether the velocity values of particles will be clamped.

• X/Y/Z: sets the min/max allowable values.

• Magnitude min/max: sets the minimum/maximum overall magnitude of particle velocity vectors.

• Variation %: the per-particle percentage of variation to apply.

#### Acceleration

• Limit acceleration: controls whether the acceleration values of particles will be clamped.

• X/Y/Z: sets the min/max allowable values.

• Accel mag: sets the maximum overall magnitude of particle acceleration vectors.

• Deaccel mag: sets the maximum overall magnitude of particle deacceleration vectors.

• Variation %: the per-particle percentage of variation to apply.

#### Spin

• Limit spin: controls whether the spin values of particles will be clamped.

• X/Y/Z: sets the min/max allowable values.

• Magnitude min/max: sets the minimum/maximum overall magnitude of particle spin vectors.

• Variation %: the per-particle percentage of variation to apply.
