	Alternatively, the elevation can be supplied by an other grid overlay, and configured using the [[Terrain elevation prequel (Water Overlay)\|Terrain elevation prequel]]. This can be useful in case you do not want to change the elevation model of your project. However, the prequel overlay must be calculated in advance and must be set to inactive in order for it to be used by the water overlay.
