Short impacts and moving trails for footsteps, attacks, explosions and projectiles.
Burst vs trail
Burst — one short event such as an explosion, sword swipe or footstep.
Continuous Trail — a moving object repeatedly leaves short local disturbances behind it.
Flow modes
Directional Burst uses the authored direction. Radial and vortex modes derive flow from the emitter center. Radius defines the footprint and Duration controls how long one emitted impact remains in the transient field.
