The Water texture map can be used to generate a procedural water texture. It can be used along with Vector Displacement (other types of displacement do not work) in order to simulate waves on the surface of water.  

Height Multiplier – Specifies a scale multiplier for the whole texture.

Resolution (pixels) – Specifies the amount of detail in the generated map.

Patch Size – Specifies the real world size of one Water texture patch, outside of which the surface is perfectly periodic.

Seed – Specifies an integer to set the starting point for the random generator. Different values produce different waves randomly.

Wind

Wind Direction – Specifies the wind direction and thus the direction of the waves.

Wind Direction Mult – Specifies a multiplier for the importance of the wind direction. Smaller values produce more variation in the direction of the waves.

Wind Magnitude – Specifies the strength of the wind creating the waves. Higher values produce larger waves.

Choppy Mult – Specifies a multiplier for the choppiness of the waves. Higher values produce sharper looking waves.

Movement Rate – Speeds up or slows down the movement of the waves. This value has an effect only in an animation.

Type – Controls how the texture is positioned on the geometry.

2D (UV Channel) – The texture uses the object UV coordinates.

Environment – This mode is currently not supported in V-Ray for Revit.

2D (UV Channel)

UV Channel/Set – Specifies the index of the mapping channel data to use. A value of 1 takes the first available channel.

Repeat U/V – Determines how many times the texture is repeated in the 0 to 1 UV square.

Lock U/V Repeat – Locks the U/V Repeat.

Offset U/V – Controls the texture offset in the U and V direction. 

Rotate – Rotates the texture (in degrees). 

Tile U/V – Tiles the texture in the U and V direction. If the option is disabled, the Default texture color is used outside the 0 to 1 UV square. Default color is found in Parameters > Color Manipulation.

Mirror U/V  – Mirrors the texture in the U and V direction separately. The option cuts the texture in the half flipping one side vertically or horizontally. This can be used to avoid seams in-between non-tileable repeated textures. 

Double-sided – This option should be enabled only if support for unique front and back face UVS is required. If enabled, channel "n"is used for front-side UVS and channel "n+1" is used for back-side UVS.
