Points Affector
Updated: 15 Sep 2026
Use points to disturb a field.
Points Affector
Method #
This node affects a field by applying positional vortex forces created around points from a particle system, or vertices of a 3D object. This can be used to make a particle system “move through” a field and appear to affect it.
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
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.
These properties control the core behaviours of the node.
Parameter Details Velocity Amount
Scale the generated affector velocities.
Point Falloff Distance
The inner falloff radius from each point. Outside of this radius, the effect will no longer apply.
Point Falloff Power
The sharpness of the falloff from each point. Higher values generate a stronger falloff at the outer falloff distance.
Randomness
The randomness of the new velocities added to the simulation.
Parameter Details Falloff Mode
Which shape to use to calculate the falloff.
- Off :
- Spherical :
- Cylindrical :
- Planar :
- Procedural :
- Cubic :
Falloff Axis
Which axis the falloff should be oriented on.
- X :
- Y :
- Z :
Falloff Direction
When using Planar mode, which directions to use to calculate the falloff.
- Bidirectional :
- Negative :
- Positive :
Falloff Easing Mode
Interpolation method used to calculate the falloff within its range of influence.
- Linear :
- Sine :
- Quadratic :
- Cubic :
- Circular :
- Bounce Back :
- Elastic :
Falloff Size X
Size of the falloff range along the X axis.
Falloff Size Y
Size of the falloff range along the Y axis.
Falloff Size Z
Size of the falloff range along the Z axis.
Outer Range
Outer range of the falloff, outside of which the falloff is no longer effective.
Inner Range
Inner range of the falloff, inside of which the falloff is fully effective.
Invert
Inverts the effect of the falloff.
Curve Power
Controls the rate of change for the falloff between the inner and outer range.
Curve
A preview of the falloff easing curve, alongside controls for editing it. Click the curve to add control points, and drag them to shape how the effect strength blends between the Inner Range (100%) and Outer Range (0%). The curve remaps the falloff gradient produced by the Size, Range and Curve Power settings.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
