Water Fountain Tutorial
4. As you move the time slider, the more the fountain goes up, now let us control over it. From the Command panel go to Space Warps, then to Forces and select Gravity from the list.
Then on the top view port drag anywhere. Then on left viewport, move the gravity icon on top of the water fountain you have created just enough on how the water goes up.
With the gravity icon still selected, go to main toolbar and select bind to Space Space Warp. See the figure. Drag to link the gravity to the super spray. Then adjust some basic parameters
Strength- this will determine the upward force super spray particles behavior, the more amount, the particles will suddenly goes down, the lesser amount, the lesser it will goes down. Adjust and play around for the strength amount until it satisfy how the your fountain goes up.
Decay- when Decay is set to 0.0, the Gravity space warp has the same strength throughout world space. Increasing the Decay value causes gravity strength to diminish as distance increases from the position of the gravity warp object. Default=0.0.
5. Now that we set already the upward strength of the fountain, the problem now is how it falls and reach the surface. From the command panel again, go to Space Warps, choose from the list Deflectors then select Deflector. Or go to the Menu Bar Create - Space Warps Deflectors Deflector.
6.Then on top viewport drag a Deflector reactor (rectangular shape) on top of the stone fountain just enough to cover it size. Name this deflector 1. While the deflector still selected, go to main toolbar and click Bind to Space Warp, then drag the deflector 1 to Super Spray Reactor. On left view port, move the deflector on its y-axis just on top of the water on the stone fountain.
Then on modifying panel, adjust the bounce amount at least 0.3, with a variation of 4.0% and friction to 10%. Now play on time slider and observe now your fountain how it behaves and reacts to the deflector. The particles bounce as it touch the water surface (deflector). You can adjust the amount as you like. But observe the height of the fountain balance with the downward force, theoretically, not much bounce will occur.
7. Now, as you observe, after the particles bounce on the first deflectors, it goes down on beneath water pond surface. Now repeat the process of creating deflectors (name this deflector 2), but now make it more bigger enough to cover the water pond surface.
From the left viewport, move it just on top on the water pond surface. Make the bounce amount to 0.1, for its gravitational downward force already lessen. Now play on time slider how it works. Save your work.
