Mesh Attractor
This node is used to attract or repel particles from the surface of a given 3D object, affect them by the velocity of the mesh, or make them flow along the surface of a mesh.
Mesh Attractor
Method #
This node is used to attract or repel particles from the surface of a given 3D object, affect them by the velocity of the mesh, or make them flow along the surface of a mesh. 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 geometry node to be connected via the Object Nodes input.
Parameters
Parameter Details Mode The affector mode.
attract, particle are attracted towards the surface of the mesh.
repel, particles are repelled away from the surface of the mesh.
follow surface, particles are attracted to the surface of the mesh and then move across the surface of the mesh once close enough to it.
velocity, particles are affected by the movement of the mesh.
Target Type 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.
Stick To Surface Distance The distance below which the particle is considered stuck to the surface.
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.
Parameter Details Blend Mode Choose how the particle colours blend to the source colours
