Here you can define the conditions for the creation of foam particles based on the splash particles' radius values:
Radius threshold
A particlessplash particle's radius ranges between 1 (birth) and 0 (death). Secondary splash particles :
- Foam will be created when
...
- the radius is
...
- smaller than the given
...
- threshold.
- A splash particle's radius is controlled with the → "Splash min | max lifetime" parameters.
