The Array operator allows you to spawn particles in circular patterns.
World Space: the selected axis will be relative to world-space.
Particle Space: the selected axis will be relative to the current particle’s transform.
Offset: the distance between the current particle and spawned particles.
Rotate around axis: controls how much rotational offset to apply to all spawned particles, around the array axis.
Min/Max angle: controls the size of the circular arc around the array axis that particles will be spawned within.
By step size: controls whether particles will be spawned at steps (in degrees) around the array arc.
By count: controls whether a static number of particles will be spawned, regardless of the size of the array arc.
Step size: the spawn step size, in degrees.
Count: the spawn count.
Move outwards: when enabled, spawned particle velocities will be affected such that they move outward from the current particle.
Velocity: the scale of the outward velocity vector to apply to spawned particles.
Divergence: controls the degrees of random divergence to apply to outward velocity vectors.
