Sometimes, when we are simulating splashes, they appear be under control but then, there are explosions due to the collision with objects. In order to remove these sort of explosions, it is good to put a KCollision daemon to kill the particles which are colliding against the objects. The result of the simulation is more natural.
Another optimization is simulating the splashes putting the objects in cache mode. Usually, in this sort of scenes, the main fluid will affect to the objects but not splashes. For this reason, it is good to put the objects in cache mode too when simulating splashes to avoid that RF takes more time to simulate due to the objects and splashes calculations. In this scene, the kcollision will affect to the “plain001_4” object (terrain object) and not rocks or branches
