After months of work, I’ve released Calysto Water Engine — a PCG-driven water system for Unreal Engine 5
Hi everyone! I’ve released Calysto Water Engine, a procedural water creation system for rivers, lakes, and oceans.
My goal was to create a practical, artist-friendly workflow for open worlds—not only an ocean shader. The system lets you draw water directly in the level, generate terrain-aware river paths and directional flow, and connect the results to shorelines, underwater effects, interactions, buoyancy, audio, weather, and gameplay systems.
Much of the scene preparation is generated in the editor through PCG, helping keep the runtime workload practical for larger environments.
It works as a complete standalone system, with optional integration for using the generated water data inside Calysto World.
