A water system library for s&box that renders seas, lakes and rivers with waves, ripples and coast masking, and ships sample gameplay like a buoyant boat, swimming and underwater audio. It builds river, lake, junction and estuary meshes on CPU from spline control points, tiles and triangulates them, then uploads to GPU via a WaterNetwork component that handles sampling, rendering and sea hole masking. Post effects and small utilities round it out, with most logic living in geometry builders and partial WaterNetwork files.
Editor-side water authoring tools. Adds tools to create and edit a WaterNetwork with rivers, lakes, and sea, draws gizmos for curves and flow, and offers sidebars for properties with undo. It has picker utilities for ray-based selection, handles for nodes and tangents, and overlay rendering to visualize the network in the scene view.
