Turbulence Affector
Updated: 1 Jul 2025
Applies Turbulence to physics objects.
Turbulence Affector
Method #
This node applies turbulence to the motion of physics objects. This is typically used to apply local variations to physics objects motion, and simulate small gusts of wind. The motion is generated by using a smoothed noise field for both the direction and the magnitude of the applied velocity.
All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain.
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 The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local y-axis.
Scale Z The objects scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the 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.
Parameter Details Amount Strength the affector has on the affected physics objects.
Noise Scale Scale the size of the generated noise. Higher values will given denser and more erratic motion, while lower values will creater smoother and more stable motions.
Noise Threshold Sets a minimum amount the noise must be pushing beyond to have an effect on the affected physics objects.
Animation Rate How quickly the turbulence animated and changes over time.
Animation Time Offset Manually control how the turbulence animation is changing oer time by offsetting it in time directly.
Update Time Mode Change how the affector uses time.
- Locked To Timecode : The effect is synchronised with the timecode, so changes in time will always yield the same results.
- Running / Loopable : The effect is generated on a separate time to the timecode, ignoring composition loops. Useful for Real-Time exports, where content needs to play indefinitely. Not suitable for looping videos.
Dampening Softens the motion applied to the objects to smooth out any erratic motion from the affected physics objects.
These properties control where an affector can affect the physics objects.
Parameter Details Use Falloff Enable falloff from the position of the affector.
Falloff Shape Select which shape to use to draw falloff from.
- Sphere : Falloff is calculated radially outward from a point.
- Cylinder : Falloff is drawn radially outward from a line.
- Plane : Falloff is drawn outward from a plane.
Falloff Shape Orientation Select which axis to draw the shape along. Only available for cylinder and plane.
- X : Faces along the x axis.
- Y : Faces along the y axis.
- Z : Faces along the z axis.
Outer Range The maximum range outside of which the affector has no effect.
Inner Range The inner range within which the affector has full affect.
Falloff Curve Power How quickly the falloff decreases to the outer falloff.
Invert Falloff Inverts the strength the affector will have on the objects, based on the falloff.
