Method
This node affects particles by positional vortex forces created around points from another particle system, or vertices of a 3D Object. This can be used to make one particle system “move through” another and appear to affect it.
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. |
| Point Falloff Distance | The radius of falloff of effect from each point. |
| Point Falloff Power | The sharpness of the falloff from each point. |
| Radius | Alter the outer radius at which the affector is no longer effective. |
| Randomness | How much randomness is added in the particles movement. |
| 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 |
|---|---|---|
| Point Source | The source of the point data. | Particle Root Node |
| Mask Node | Mask out areas that particles cannot spawn. | Image Plane |
| 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.
