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.

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

Parameters

These properties control the core behaviours of the node.

ParameterDetails
Spawn ModeChoose where particles move to, mesh polygons or mesh vertices.
Use ColoursToggle whether particles use the same colours as the input object.
RadiusAlter the outer radius at which the affector is no longer effective.
RandomnessHow much randomness is added in the particles movement.
Velocity ScaleScale the strength of the affectors velocity on the particles.
WeightHow strong an effect has on the particles.
Colour WeightThe amount in which the colour of the particles blends towards the target object’s colours.
StickinessControls how much the particle sticks to the surface of the shape once it reaches it.
Life Effect CoeffsHow 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.

How the mesh colours blend with the current particle colours.

ParameterDetails
Blend ModeChoose how the particle colours blend to the source colours
