This River Tool is spline based with vast material instance properties, there is object detection and distortion showing water flowing around objects and up against them, there is also added Flow Buoyancy for physical objects to float and flow down rivers at a given speed.

How to use:

Place the BP_RiverWater in the world and duplicate out the splines to the shape of the river you require.

Change the scale of each spline point to scale the river.
