Turbulence Affector
Applies turbulent velocities to a field.
Turbulence Affector
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.
Parameters
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.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details
Velocity Amount Scale the generated affector velocities.
Radius The outer radius for which the affector is active.
Inner Radius Edit the size of the inner area the affector can affect.
Randomness The randomness of the new velocities added to the simulation.
Noise Scale Scale the size of the noise for the turbulence.
Noise Threshold Limit the low end noise that will be output to the field.
Mode Choose 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.
