Spline Attractor

Spline Attractor

Attracts particles towards a spline.

Method #

This node attracts particles towards a spline shape. The particles will flow along the spline towards a goal point which moves from the beginning to the end of the spline at a rate determined by the Spline Rate parameter. The splines used by this node are extracted from a 3D object which must be connected for this node to have an effect. If The object that is connected contains no spline data this node will have no effect.

This node requires a spline to be connected via the spline input.

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.

ParameterDetails
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.

ParameterDetails
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.

ParameterDetails
Velocity ScaleScale the strength of the affectors velocity on the particles.
RadiusAlter the outer radius at which the affector is no longer effective.
RandomnessHow much randomness is added in the particles movement.
Spline RateThe rate at which the goal point moves from the start to the end of the spline.
Spline Time MinThe minimum point on the spline at which particles will be affected.
Spline Time MaxThe maximum point on the spline at which particles will be affected.
Life Effect CoeffsHow much the particles are affected by the affector at different stages of the particles life cycle. Values 1 and 2 are control points used to control a bezier curve between values 0 and 3.
