This page provides information on the V-Ray Water Map. Overview VRayWater is a procedurally generated texture. It can be used along with Vector Displacement (other types of displacement will not work) in order to simulate waves on the surface of water. An alternative way to simulate waves is Phoenix Ocean Texture. It is easier for use. For more information, see the  Mesh page . Workflow  Select the geometry and apply a single VRayDisplacement node to the selection from  V-Ray Shelf > VRayDisplacement . Go to VRayDisplacement parameters and add a VRayWater texture in the  Displacement mat.  slot. Add Displacement Control from  Attributes > V-Ray > Displacement Control . The Displacement controls will be displayed in the Extra VRay Attributes of the VRayDisplacement parameters. In the Displacement Control, set the  Displacement Type  to vector displacement as VRayWater texture can work only with this displacement type. Adjust the parameters of the VRayWater texture. Parameters Height Multiplier  – Specifies a scale multiplier for the whole texture.  See the  Height Multiplier example  below. Wind Direction  – Specifies the wind direction and thus the direction of the waves.  See the  Wind example  below. Wind Magnitude  – Specifies the strength of the wind creating the waves. Higher values produce larger waves.  See the  Wind example  below. Wind Direction Multiplier  – Specifies a multiplier for the importance of the wind direction. Smaller values produce more variation in the direction of the waves.  Choppy Multiplier  – Specifies a multiplier for the choppiness of the waves. Higher values produce sharper looking waves. Rate  – Speeds up or slows down the movement of the waves. This value has effect only in an animation.  Seed  – Specifies an integer used to set the starting point for the random generator. Different values produce different waves randomly.  See the  Seed example  below . Resolution  – Specifies the amount of detail in the generated map.  Patch size  – Specifies the real world size of one patch of the VRayWater texture outside of which the surface is perfectly periodic. Example: Height Multiplier Height multiplier = 1 Height multiplier = 2.5 Height multiplier = 5 Example: Seed Seed = 1 Seed = 3 Seed = 5 Example: Wind Direction In the following example, we can see how the  Wind Direction  parameter affects the waves. In our case, the wave angle is set to 21 degrees and in the animation the waves are moving at an angle of 21 degrees in a counterclockwise direction relative to the X axis. None of the texture parameters need to be animated to produce moving waves. Here, the  Wind Direction  is set to 21.  Wind Magnitude  is 15,  Height Multiplier  is set to 5 and  Seed  is 3.
