When you take a look at the emitter's “Particles” panel you will see that it lacks a “Resolution” parameter, because with “Dumb” particles, “Emission rate” is used to create particles. For “Liquid” particles the “Resolution” parameter is still available. The value you enter here is the number of particles which are created per second per cubic metre.When a splash or foam particle is created, it has a radius of 1.0 and RealFlow calculates an expected lifetime based on the settings under “Min life time” and “Max life time”. During its lifetime, the radius is constantly decreasing and when it reaches 0.0, the particle dies. When a splash particle hits the core fluid surface it will be deleted immediately regardless of its current lifetime.
Curvature threshold
You can use the fluid's curvature to trigger the generation of splash particles. This value represents the minimum curvature for the creation of splashes. Curvature can also be seen as the fluid's “roundness”. With higher values, the fluid's borders/surface has to have a greater curvature to start the emission of splashes. With small values, the parameter is less sensitive and creates particles even in areas with a low curvature. Valid values range between 0 and 1.
