RealFlow

RealFlow is a 3D simulation tool with plugins that let you create realistic water and physics effects for things like visual effects and motion graphics. You can use it to make stuff like pouring liquids, ocean waves, waterfalls, smoke like particles, and even object collisions. It also lets you simulate rigid and soft bodies, so objects can crash, bend, break, and interact in a more natural way. On top of that, it has features like gravity and wind controls, automatic meshing, particle tools, texture support, and easy export options for other 3D software.
