Enhanced Water Shader using Velocity Flow Maps

Development video showcasing an enhanced water shader using Velocity flow maps to create abitrarily flowing water. Based on the white paper from Valve for Portal 2 Water shader. Youtube encoding seems to have made the water very difficult to see clearly . Note that the ripples are created purely via the algorithm, the normal map used has no animation in it. This has the benefit of cutting down a bit on memory requirements for water. Before it had to cycle over a number of frames in the normal map for standard pre-existing Source SDK water shader
