Particle Nodes
Particles are a large number of duplicated objects that automatically animate. They are used to
create elements like falling rain, fireworks, smoke, pixie dust, and much more. There are
endless possibilities. Particles in Fusion consist of a set of nodes that are strung together in a
chain for generating, modifying, and rendering particles in a 2D or 3D scene.
To begin, every particle system you create must contain two fundamental nodes:
pEmitter: Used to generate the particles and control their basic look,
motion. and behavior.
pRender: Used to render the output of the pEmitter into a 2D or 3D scene.
When creating particles, you only ever view the pRender node.
The remaining particle nodes modify the pEmitter results to simulate natural
phenomena like gravity, flocking, and bounce

The pAvoid node
pAvoid Node Introduction
The pAvoid node is used to create a region or area within the image that affected particles
attempt to avoid entering and crossing.
It has two primary controls. The first determines the distance from the region a particle should
be before it begins to move away from the region. The second determines how strongly the
particle moves away from the region.
A pAvoid node creates a “desire” in a particle to move away from a specific region. If the
velocity of the particle is stronger than the combined distance and strength of the pAvoid
region, the particle’s desire to avoid the region does not overcome its momentum and the
particle crosses that region regardless.
