WebMapServiceRasterOverlay Shader in UE?

I now have the shp information of a river, and I loaded it in Cesium for UE’s CesiumWebMapServiceRasterOverlay through geoserver. However, it can only be rendered in the style of VMS in UE. How can I replace the style from VMS with the waterbody material in UE to render these vector ? The layer key of CesiumWebMapServiceRasterOverlay does not seem to work like in CesiumPolygonRasterOverlay

You will need to create a custom Material that accesses the raster overlay and uses it to select between a land effect and a water effect. This tutorial explains how to create custom materials:
