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.

Transform

Name Description
Position X Move its position along the x-axis in local space.
Position Y Move its position along the y-axis in local space.
Position Z Move its position along the z-axis in local space.
Rotation Heading Rotate the object about the x-axis.
Rotation Pitch Rotate the object about the y-axis.
Rotation Bank Rotate the object about the z-axis.
Scale X Scale along the x-axis.
Scale Y Scale along the y-axis.
Scale Z Scale along the z-axis.

Inherit Transform Channels

Toggle which transform channels should be inherited. By default, all are on.

Attributes

Name Description
Velocity Scale Scale the strength of the affectors velocity on the particles.
Radius Alter the outer radius at which the affector is no longer effective.
Randomness How much randomness is added in the particles movement.
Spline Rate The rate at which the goal point moves from the start to the end of the spline.
Spline Time Min The minimum point on the spline at which particles will be affected.
Spline Time Max The maximum point on the spline at which particles will be affected.
Life Effect Coeffs How 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.

Inputs

Name Description Typical Node Input
Object Nodes The source object for the splines. 3D Object
Affected Emitters Choose which emitters can be affected by the affector. Primitive Emitter
Procedural Falloff Use the SDF values from a procedural system to dictate the falloff. Procedural Root
Transform Modifier Links all transform properties to the input node. Null
Target Node Always faces the x-axis towards the inputs anchor point. Null
Local Transform Override Override the transformation values of the node, relative to its parent. Null

Outputs

All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain.
