Turbulence Affector

Turbulence Affector

Applies turbulent velocities to a field.



Method #

This node applies turbulence to the movement vectors of a field system, applying a noisy motion with a large range of noise shapes.

The outputs from this node are just its transforms, useful for having multiple nodes follow the same motions without controlling each of their transforms individually.


These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

Velocity AmountScale the generated affector velocities.
RadiusThe outer radius for which the affector is active.
Inner RadiusEdit the size of the inner area the affector can affect.
RandomnessThe randomness of the new velocities added to the simulation.
Noise ScaleScale the size of the noise for the turbulence.
Noise ThresholdLimit the low end noise that will be output to the field.
ModeChoose how the turbulence effect is calculated.
  • Repel : Pushes the fields away from the affector origin point.
  • Attract : Pulls the field towards the affectors origin point.
  • Turbulent : Pulls and pushes the field with turbulent forces.
