Box Emitter (CPU and GPU)

The Box emitter enables spawning of particles along the shapes axial coordinate system. This allows you to create complex planar and rectangular effects.

The following is an example of the Box emitter in the Preview viewport.

The following are parameters for the Box emitter.

Box Emitter Parameters

Parameter Description
Emitter Size XYZ Sets the size of the box emitter in meters.

Valid values: 0+ (radius)

Default value: 5

Confine XYZ Confines the particles to render within the box size on each axis.

Default value: false

Spawn Pos XYZ XYZ values define the spawning position away from the emitter in emitter space. You can set a Random value and Strength over Emitter Lifetime curve.

Valid values: any

Default value: 0, 0, 0

Spawn Pos XYZ Random For additional random layering, XYZ values define the range of random spawning in both directions, away from the spawn position. You can set a Random value and Strength over Emitter Lifetime curve.

Valid values: any

Default value: 0, 0, 0

Velocity XYZ XYZ values define the velocity applied to particles in world space. The velocity direction also sets the axis in which velocity spread occurs around. You can set a Random value and Strength over Emitter Lifetime curve.

Valid values: any

Default values: 0, 0, 0

Velocity XYZ Random For additional random layering, XYZ values define the random velocity applied to particles in world space. You can set a Random value and Strength over Emitter Lifetime curve.

Valid values: any

Default value: 0, 0, 0
