A Houdini procedural tool for creating rivers in Unreal Engine. A river and its terrain (banks, cliffs, thresholds) follows the cusom spline input in Unreal. A river contains the water and terrain surfaces. Natural parameters, such as intensivity of the noise (water and terrain), width, form, etc. are made with Python and can be set in Houdini or Unreal.
