The Branch operator spawns child particles which travel at predictably-divergent angles relative to parent particles. It can be used as the basis for effects like growing frost, lightning, etc.
Distance: the minimum distance a parent particle must travel before spawning a child.
Angle: the angle of divergence applied to spawned particles’ velocity trajectory.
Max: the maximum number of particles to spawn at each branch event.
Max depth: the maximum number of recursive branches that may be spawned.
Increasing max depth increases the number of successive recursive steps the branching algorithm can take. For example, a max depth of 2 means that particles which enter the event may spawn children, and those children may spawn children of their own, but that third group of children (the grand-children of the original particles) may not spawn further children. Increasing the max depth will exponentially increase the total number of particles that will be spawned over time.
Inherit %: the amount of velocity child particles will inherit from parent particles.
Inherit %: the amount of scale child particles will inherit from parent particles.
Min depth enable: controls whether child particles that reach a certain depth will test TRUE for output.
Min depth value: sets the minimum depth value required for child particles to satisfy the condition.
