Class Documentation

A physics modifier that sets the particles' scale. It runs on each step after the integration. The scale is InitialScale * KeyedScale, multiplied by the factor of ScaleByVelocity when that is enabled, and then by the emitter instance's scale.

Properties

InitialScale

Embed<VfxVector3DynamicProperty> = { "Vector3": {} }

Type history (2 revisions)

15.23 - 15.23 Embed<ValueVector3>
since 15.24 Embed<VfxVector3DynamicProperty>

Documentation Edit documentation

Per-axis scale of the particle, evaluated once per particle at spawn. Left at its default, it is 1 on every axis. Required: if the driver is null, the modifier does nothing.

IsUniform

Flag = false

15.24

Documentation Edit documentation

Uses the X component of the scale for all three axes.

KeyedScale

Embed<VfxVector3DynamicProperty> = { "Vector3": {} }

Documentation Edit documentation

Multiplier on InitialScale, evaluated on every step. A curve over the particle's age here grows or shrinks the particle over its life.

ScaleByVelocity

16.10

Default value

{
  "MaxScaleFactor": { "Vector3": null },
  "Enabled": false,
  "MinScaleFactor": { "Vector3": null },
  "VelocityThreshold": 0
}

Documentation Edit documentation

An extra scale factor taken from the particle's speed. See VfxScaleByVelocityData.
