 A water surface is not seldomly a popular game component. We do not provide directly a water surface component, but it is quite easy to setup one.

+=== Properties ===
+Besides the textures, the water material source provides a few configuration properties to influence water look.
+^ Property ^ Description ^
+| Diffuse | The material shader uses this color as main color for water. |
+| Specular | The specular color interacts with the applied specular color map and configurates its intensity. |
+| WaveSpeed | Defines how fast waves are moving. |
+| WaveSize | Defines the amplitude of waves, which means how high or low waves are simulated. This value do not manipulate mesh vertices (only by displacement mapping). |
+| Displacement | Defines the factor of vertex displacement based on the displacement map or normal map. |
+| ReflCorrection | By this value you can modify the color of reflection, default value: Vector3D(1.0, 1.0, 1.0, 1.0) |
+| RefrCorrection | By this value you can modify the color of refraction on water surface, default value: Vector3D(1.1, 1.1, 1.1, 1.0) |
