Wet & Foam - Foam Creation

In contrast to the “Foam” emitter, this panel provides only a single parameter. This reduced parameter set is enough to create and control the foam particles. The creation of foam itself is triggered by the splash particles.

Radius threshold

Foam particles are generated from splashes and this parameter determines the minimum radius of the splash particle that is able to produce foam. Splash particles with a radius below this value cannot contribute to foam anymore. That is not only interesting for controlling the amount of foam, but also if you want to use mist to fragment the splashes: The basic idea is that after the fragmentation into mist, the splash particles are so tiny that they will not create more foam.
