Splash & Foam - Foam Creation

Here you can define the conditions for the creation of foam particles based on the splash particles' radius values:

Radius threshold

Foam occurs when splash particles enters the fluid's surface, and a splash particle's radius ranges between 1 (birth) and 0 (death):

• Foam will be created when a splash particle's radius is smaller than the given threshold.
• A splash particle's radius is controlled with the → "Splash min | max lifetime" parameters.
