It’s not often something makes you stop in your tracks and just watch, but William Faucher's EasyWaterscape is a tool that did just that when I saw it – this water sim looks incredible, but importantly it brings a level of AAA-style ocean simulation to Unreal Engine and wraps it in a tool artists can actually enjoy using.
Water simulation is something gamers love to dwell on; just look at how incredible AC Black Flag Resynced looks, but making convincing water, and doing it in Unreal Engine, has always felt like a challenge easier said than done. Artists need to tweak wave settings for half an hour, realise the shoreline looks wrong, then spend another hour trying to get the foam to behave as our minds think it should. It's one of those effects that's easy to appreciate, loved by gamers, and surprisingly fiddly to create.
That's why William Faucher's new Unreal Engine tool caught my eye and stopped me in my tracks. If you've spent any time browsing Unreal tutorials, you'll probably know Faucher as the creator of EasyFog, one of Unreal Engine's better-known environment plugins. His latest release, EasyWaterscape, takes aim at another headache: creating oceans, lakes and coastlines that look expensive without requiring you to become a water simulation expert first or to turn to complex software like Houdini.
The big selling point is that this doesn't rely on simple fake wave animations. EasyWaterscape uses an FFT (Fast Fourier Transform) ocean simulation based on Tessendorf's approach and JONSWAP wave spectra, techniques commonly used in games and visual effects, so the surface behaves much more like real water, with long rolling swells layered alongside smaller waves and fine ripples. The result looks far more natural than the looping water effects you'll often spot in indie games.
What I like most, though, is that Faucher has spent as much time thinking about the workflow as the technology. Instead of exposing dozens of intimidating controls, the system is controlled through a Blueprint actor, complete with presets for calm lakes, rough seas and stormy oceans. There are plenty of smart additions too. Shorelines generate foam automatically, floating objects can interact with the water through built-in buoyancy, and there's a tile-free rendering mode designed to avoid that obvious repeating pattern that can make even beautiful oceans feel like giant animated wallpapers.
It also supports both endless oceans and contained lakes, with the water following the camera to create the illusion of an infinite sea. Better still, there's no C++ setup required, making it easier to drop into an existing Unreal Engine project and start experimenting.
The timing makes sense: while Unreal Engine has never looked better, with details of Unreal Engine 5.6 and the tease of UE6 impressing, expectations have risen alongside them. If you're building environments in 2026, players notice poor water quality almost as quickly as they notice poor lighting. It's one of those details that can instantly sell a scene, or completely undermine it, and gamers love to pick up on these things.
EasyFog became popular because it removed a lot of technical friction in building atmospheric environments, and EasyWaterscape looks like it offers the same ease of use. For anyone building coastal environments, open-world games or cinematic scenes in Unreal Engine, this looks like one to keep an eye on. And even if you're not a game artist or dev, the visual spectacle and realism of scenes created in EasyWaterscape impress enough to make you stop, look, and enjoy.
