ControlWhat it does
GravityDown, Zero-G, Up or Sideways, or drag the dial for any direction and strength.
TimeHow fast the simulation runs. Below 1× is slow motion, above is sped up.
DropletDroplet size. Bigger droplets fill more of the frame with the same budget and smaller files.
Droplet budgetThe most droplets alive at once: 1.5k, 3k, 4.5k or 6k.
When fullWhat happens at the budget. Keep pouring shrinks away the drops you’d least notice: out of shot first, then stray spray, then the oldest. Oldest first shrinks away the longest-lived drops, which suits fountains and falls. Hold removes nothing; sources pause until drops leave the frame or drain.
WallsClick an edge of the frame to close it. Open edges let liquid spill out of shot.
Stage colorDark, Light or Checker. Only for the lab; the bake lands on your real comp.
RandomnessReroll gives the same scene a different splash.
