Starting point for splashes is always an existing → core fluid and → splash and/or → wet simulation.




Scene Setup

  • Set the domain's and splash emitter's simulation state to → “Cache” (“yellow rocket”).
  • Other, already simulated Hybrido secondary fluids emitters have be set to “Cache” as well.
  • Add a “Mist” node from the “Hybrido” shelf.
  • Reset the scene.



 

What you can see now is a bounding box with a dimension of 10 m x 10 m x 10 m. The box can be positioned and scaled with the settings under Node Params > Node or the W and R keys. Mist is

  • only created inside this box and it cannot leave its domain
  • not affected by “k” daemons.

 

Open the → “Mist” parameter section for further adjustments:




  • “Cell size” can be set independently from the domain's own → “Cell size” value.
  • “Solver” should be “Fast” – the results will be good enough.
  • “Radius threshold” is the most important parameter, because it controls the amount of foam (see below for more information).

 

The "Radius threshold" parameter depends on the splash particles' lifetime.




  • When a splash particle is created its radius is 1. Depending on the lifetime settings, the particle's radius becomes smaller over time until it reaches 0.
  • Lifetime is adjusted under → "Splash Dynamics" or → "Wet Dynamics".
  • You have to decrease these parameters in most cases, e.g. to 1.5 s ("Splash | Wet min lifetime") and 2.0 s ("Splash | Wet max lifetime").
  • Smaller thresholds will reduce the amount of mist.
