Using affector nodes¶
Affector nodes apply force to particles. For an affector node to apply force to particles, it must be a direct child of the Particle System node on the particles of which you want to apply that force. To create different particle effects, you can use multiple affector nodes in a single Particle System node and use the Render Transformation or Layout Transformation properties to position them. To release particles that you affect with affector nodes, use emitter nodes. See Using emitter nodes.
Types of affector nodes¶
Kanzi Particles includes these types of affector nodes:
Particle Curl Affector defines an infinite force field that a curl noise function randomly distorts.
Particle Force Affector applies to particles a directional force.
Particle Point Affector pulls particles towards or pushes particles away from itself.
Using the Particle Curl Affector¶
Particle Curl Affector defines an infinite force field that a curl noise function randomly distorts.
Use this affector to create natural looking movement for particles. With high number of particles this affector uses a lot of CPU resources.
Use these properties to adjust the affector:
Strength property sets the magnitude and direction of the force that this affector applies to particles.
Scale property sets the wavelength multiplier of the noise field.
Animation Speed property sets how rapidly the noise field evolves.
Tightness property controls the amount that flow affects particles. In other words, with this property you set the drag of the flow defined by the noise field. Higher tightness makes particles flow along the field. Use high values to achieve fluid-like motion and low values when you want other affectors and forces to have stronger impact on the particles.
Flow Speed property controls the speed of the flow.
Using the Particle Force Affector¶
Particle Force Affector applies to particles a directional force.
Use these properties to adjust the affector:
Force property controls the strength of the force on each axis.
Layout Transformation and Render Transformation Rotation property field changes the direction of the force.
Using the Particle Point Affector¶
Particle Point Affector pulls particles towards or pushes particles away from itself.
Use these properties to adjust the affector:
Force property sets the magnitude of the force that this affector applies to particles.
Range property sets the area in Kanzi units within which this affector applies force to particles.
