Here's how to do it,
first create your water ripple shader...
Then at the end frame, set completion and dampening to 100% (dampening
is how tall it is, as a radial gradient function)...
Now, if you want the ripples to spread out more, as in more ripples
than what you now get...
Just open the sequence tray, and click the little arrows next to your
shader to see it's params, then click the same arrow for bump (or
color if that's where your ripple function is, and you're using it for
AGrooves as a heightmap)...
Now, the Time parameter is the one controlling completion click it's
tweener (if you don't know what that is, it's the rectangle between
two keyframes), and set it to an oscillate tweener with sawtooth
function with 100% up phase (this has to be done in the assembly room,
as tweener properties don't show up in the shader room)...
Now you should have an animation of a ripple that has many ripples
that fade out over time...
