Method
This node is used to attract or repel particles from the surface of a given 3D object. This is typically used to make particles form into a given shape. Particles will use the closest point on the object’s surface to move towards or away from; this may be offset randomly using the Randomness attribute to create a noisier shape.
This node requires a 3D object to be connected via the Object Nodes input.

Attributes
| Name |
Description |
|---|
| Spawn Mode |
Choose where particles move to, mesh polygons or mesh vertices. |
| Use Colours |
Toggle whether particles use the same colours as the input object. |
| Radius |
Alter the outer radius at which the affector is no longer effective. |
| Randomness |
How much randomness is added in the particles movement. |
| Velocity Scale |
Scale the strength of the affectors velocity on the particles. |
| Weight |
How strong an effect has on the particles. |
| Colour Weight |
The amount in which the colour of the particles blends towards the target object’s colours. |
| Stickiness |
Controls how much the particle sticks to the surface of the shape once it reaches it. |
| 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. |
Blending
| Name |
Description |
|---|
| Blend Mode |
Choose how the particle colours blend to the source colours |
Inputs
| Name |
Description |
Typical Node Input |
|---|
| Object Nodes |
The source meshes for the particles ot be attracted to. |
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.
