# Evaluate Water Simulation Displacement
|
||
|
|
|
||
|
|
This node calculates water surface displacement.
|
||
|
|
|
||
|
|
The High Definition Render Pipeline (HDRP) uses this node in the default water shader graph. See the HDRP documentation for more information about [the Water System](https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@14.0/manual/WaterSystem.html).

|
|
| **Name** | **Direction** | **Type** | **Description** |
|

|
||
|
|
| **PositionWS** | Input | Vector3 | The position of the water surface vertex in world space. |
|
||
|
|
| **BandsMultiplier** | Input | Vector4 | The amount to dampen displacement for each water band. Bands are different wave frequencies that create swells, agitations or ripples on the water. |
|
||
|
|
| **Displacement** | Output | Vector3 | The vertical and horizontal displacement of the water. |
|
||
|
|
| **LowFrequencyHeight** | Output | Float | The vertical displacement of the water surface. This doesn't include ripples. |
|
||
|
|
| **SSSMask** | Output | Float | Mask that defines where the water surface has subsurface scattering. |
