Water Fog Color   Opens the Color Picker so you can change how underwater fog appears. Fog Density Exponent   Controls how dense the water fog is and how far you can see underwater. Has no underwater effect when Underwater Fog Modifier is 0.00. Underwater Fog Modifier   Boosts or lessens Fog Density Exponent when you're underwater. Has no effect on the water's surface. Big Wave Direction   Controls where and how fast the large-scaled version of the normal map moves in the X and Y directions.

Reflection Wavelet Scale   Controls the scaling of the three wavelets that make up the water. Changes may be subtle and are easier to see with low Fresnel Scale settings. Fresnel Scale   Controls how much light is reflected at different angles. See Fresnel. Fresnel Offset   Controls how much light intensity is reflected. Little Wave Direction   Controls where and how fast the the small-scaled version of the normal map moves in the X and Y directions.

Refract Scale Above   Controls how much light is refracted from looking above the surface of the water. Refract Scale Below   Controls how much light is refracted from looking from below the surface of the water. Blur Multiplier   Controls how waves and reflections are mixed. Higher values appear brighter. Normal Map   Opens Pick Texture so you can set what normal map is layered across the water to determine reflections and refractions. A normal map is a specially-prepared image to simulate depth, but you can use any texture here.
