Use this effect to create a ripple and add a refractive look to the surface of your image. This simulates how an object distorts when it is just beneath the surface of moving water or behind a refractive object such as frosted glass.

Ripple Amount

Specifies the size of the ripples. Animating this property creates the effect of moving water.

Refractive Index

Specifies the ratio of the light’s velocity as it passes from a rarer to a denser medium.

Bump

Specifies the grain amount on the surface.

Depth

Specifies the depth of the surface through which you are viewing the image. For example, in the case of simulating an underwater object, adjusting this value changes how deep an object appears to be in the water.
