Points Affector

Points Affector

Use points to disturb a field.

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.


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.
Point Falloff DistanceThe inner falloff radius from each point. Outside of this radius, the effect will no longer apply.
Point Falloff PowerThe sharpness of the falloff from each point. Higher values generate a stronger falloff at the outer falloff distance.
RadiusThe outer radius for which the affector is active.
RandomnessThe randomness of the new velocities added to the simulation.
