# Pack Water Vertex Data
|
||
|
|
|
||
|
|
This node packs multiple water properties into two UV properties for the vertex context.
|
||
|
|
|
||
|
|
The High Definition Render Pipeline (HDRP) uses this node in the default water shader graph. Don't modify the settings of this node. 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).
