To the top
Lower values smooth the Caustics surface.
Specifies the roundness of the waves by blurring the water surface layer. High values eliminate detail. Low values show imperfections
in the water surface layer.
Specifies depth. A small disturbance in shallow water moderately distorts the view of the bottom, but the same disturbance in deep
water distorts the view greatly.
Affects the way the light bends as it passes through the liquid. A value of 1 does not distort the bottom. The default value of 1.2
accurately simulates water. To add distortion, increase the value.
Specifies the color of the water.
Controls how much of the bottom layer is visible through the water. If you want a milky effect, increase the Surface Opacity and
Light Intensity values; a value of 0 results in a clear liquid.
Set Surface Opacity to 1.0 to perfectly reflect a sky later. With a suitable texture map, you can use this technique to create the effect of liquid
mercury.
Displays the caustics, the concentrations of light on the bottom surface, caused by the lensing effect of the water waves. This
control changes the way everything looks: The dark spots of the waves get much darker, and the light spots get much lighter. If you don’t set a
value for this control, the effect distorts the bottom layer when the waves pass over it, but it doesn’t render the lighting effect.
Sky controls
Specifies the layer above the water. Scaling makes the sky layer larger or smaller. If the edges of the sky layer show, scale the layer up.
Scaling down is useful for tiling a layer to make a complex pattern.
Specifies how a scaled-down sky layer is tiled. Once uses only one tile, basically turning tiling off. Tiles uses the traditional tiling
method of abutting the right edge of one layer tile to the left edge of another layer tile. This option works well if the layer contains a repeating
pattern, like a logo, that needs to read a certain way. Reflected abuts each edge of a layer tile to a mirrored copy of the tile. This option can
eliminate a hard edge where the two tiles meet.
Specifies how to handle the layer when it is smaller than the composition. Intensity specifies the opacity of the sky layer.
Convergence specifies how close the sky and the bottom or water layer appear, controlling the extent to which the waves distort the sky.
Foam effect
This effect generates bubbles that flow, cling, and pop. Use the controls for the effect to adjust attributes for the bubbles such as stickiness,
viscosity, life span, and bubble strength. You can control exactly how the foam particles interact with each other and with their environment, and
specify a separate layer to act as a map, controlling precisely where the foam flows. For example, you can have particles flow around a logo or fill
a logo with bubbles.
This effect works with 8-bpc color.
