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.
