Drag slowly upward or downward on the Phase
spinner.
Increasing the Phase value moves the waves
inward, and decreasing it moves the outward.

To simulate an object dropping in liquid, use
the Decay setting.

decrease with the distance from the center of
the effect. This is the effect you get when an
object perturbs the water surface, and the waves
lose energy as they move away from the point
of impact.

Gizmo—At this sub-object level, you can transform
and animate the gizmo like any other object,
altering the effect of the Ripple modifier.

Center—At this sub-object level, you can translate
and animate the center of the ripple effect, and
thus the shape and positions of the ripples.
