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 surface's “roundness”. With higher values, the fluid's borders/surface must have a stronger curvature to start the emission of splashes. With small values, the parameter is less sensitive and creates particles even in areas with low curvature. Valid values range between 0 and 1 Any positive value can be used.
Speed threshold
It is also possible to use the underlying grid fluid speed for the splash creation process. If the fluid's velocity is below the adjusted threshold, no new splashes will be generated. “Speed threshold” is very easy and effective way to reduce the amount of splash particles. The parameter's unit is metres per second [m/s].
