**SELECTIVE BRUSH DENSITY**

Set TopicsSET TOPICAug 5, 2026Original source

Visible issue: “the water seems to flow endlessly from the character”

  1. ninja picks up point-like inputs (bones, object pivots) - and by default uses them to generate density - eg.: we set up a torch, canvas empty, torch head generates flames/smoke.
  2. For DENSE type water setups (like Creek-1, Creek-2, Dense Lake, Dense Sea), we would like to selectively generate density. For example: particles generate density - as they function as “water sources” - while Pawn Bones and Objects only generate velocity --- so they stir the fluid, but do not function as density source.
    .
    Key param: /LiveComponent /LiveInputPoints /BrushKillers /SelectivelyKillBrushDensityKeepVelocity --- in case you set it to “1”, bones and objects will not generate density.
