Particle-Particle Collision Affector
Updated: 17 Feb 2025
Allows particles to collide with each other.
Particle-Particle Collision Affector
Method #
This node allows the particles to collide with each other while simulating, with a defined collision radius. Combined with the Particles To Point Geometry node, and a similar collision radius/sphere size, it is possible to simulate simple ball physics between the particles.
Parameters
These properties control the core behaviours of the node.
Parameter Details Particle Collision Radius Radius around a particle in which it will calculate colliding with others particles.
Collision Velocity Scale Scales the velocity of the particle after a collision so they can be made to slow down.
Collision Softening Reduce the impact of collisions between particles.
Dimension Choose whether the effect is 2d or 3d.
Simulation Steps Duration of each calculation step, controlling the precision and speed of the simulation.
