Method
This node simulates a spring-like effect between a particle’s current position and its original emission position, making it spring back towards the point it was emitted from over a period of time. This can be used to restore particles to their original emitted form, or as part of cloth simulations.

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 |
| Spring Length |
The scaling applied to the rest length of the generated springs. |
| Spring Strength |
The strength of the spring effect. Larger values will make spring forces greater and particles will move more quickly. |
| Spring Dampening |
The dampening applied to the spring forces. |
Inputs
| Name |
Description |
Typical Node Input |
| 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.
