Since forces between particles only affect the fluid and nothing else, this option is strictly limited to emitters. Scripted daemons, on the other hand, can either affect particles and rigid bodies. The difference is that you are going to introduce external forces which can act like RealFlow’s standard forces, for example gravity. With a scripted daemon you can model your own force fields, such as vortices or falloffs. The great advantage with this type is that they can be treated like any other daemon. In other words: you can make them exclusive to certain nodes or (de-)activate them at a certain point in time, for example. Scripted RealWave modifiers are also possible and with RealFlow 5 an important change has been introduced. In former versions it was only possible to calculate vertex displacement along the surface’s height axis. This limitation has been removed, so you are now , and you are free to perform calculations for all three axes. This extension helps you to create completely customised wave types, for example breaking waves, with Python scripting. One of the best applications of scripted waves is the translation of an image’s grey scale values into height information. With this method you are able to create wave simulations out of a sequence of images.
