Mesh Attractor
Attract or repel particles from a mesh.
Mesh Attractor
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.
Parameter Details
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.
How the mesh colours blend with the current particle colours.
Parameter Details
Blend Mode Choose how the particle colours blend to the source colours
