Plug-In Basics: The Splash plugin consist of two main types of objects:
Pool - the water area where the action takes place. It is situated in Create/Fluid Mechanics panel. After creating it you can change the mesh Density (the greater density the smother ripples will be) and other parameters which will be described later.
Stones - the objects that fall or move in the water. They are in the Helpers/Fluid Mechanics panel. There are two types of Stones: Impact Stones (I-Stone) and Wake Stones (W-Stone). I-Stones lets you to make splashes and ripples on the water when something falls into the water. W-Stone is a helper that can be linked to an object that moves on the water surface (water crafts, ships, boats, animals like ducks or swans and others) and make wakes that are left after the floating object.
