Point Emitter (CPU and GPU)

The Point emitter spawns particles in a spherical distribution from the origin. This allows you to control the spread angle to create complex conical and spherical effects.

The following are parameters for the Point emitter.

Point Emitter Parameters

Parameter Description
Spawn Offset Offsets the spawning of particles spherically at distance from the emitter origin.

Valid values: 0+ (radius)

Default value: 0

Spawn Pos XYZ XYZ values define the spawning position away from the emitter itself 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 around which velocity spread occurs. 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

Velocity Spread Restricts the angle of spherical distribution in the direction of the velocity XYZ vector. For example, a value of 360 = Sphere, 180 = Hemisphere, and so on. You can set a Random value and Strength over Emitter Lifetime curve.

Valid values: 0 – 360

Default value: 360
