The Array operator allows you to spawn particles in linear/circular patterns.
“Linear”, in this context, just means positionally along an X/Y/Z axis. For example, if you have a single planar particle and want to create a stack of them, you can use the Array operator to generate a number of particles offset along the Z-axis of the world. This will stack the new particles on top of each other.
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.
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.
Align rotation: when enabled, spawned particles will be aligned to the vector from their position to their parent.
X/Y/Z: the axis of a spawned particle’s transform to align to the vector between its position and the position of its parent.
Flip: flips the axis of alignment.
Delete parent: when enabled, the parent particle of the new array particles will be deleted.
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.
World Space: the spread axes will be relative to world-space.
Particle Space: the spread axes will be relative to the current particle’s transform.
X/Y/Z Spread: the distance between each spawned particle along the specified axis.
Center spread around parent: when enabled, the spread of the group of spawned particles will be centered around the parent particle position. When disabled, the spread will be offset from the parent particle position.
