Dynamic Real Water v5.7 is a GPU-accelerated FFT water simulation plugin for Unreal Engine 5. It features compute shader-based FFT wave generation, multi-LOD grid streaming, a modular physics body system, asynchronous buoyancy physics via GPU readback, analytical foam, semi-analytical caustics, depth map generation, and dynamic underwater effects. It is suitable for a wide range of applications, including games, cinematics, interactive experiences, and simulations where visual fidelity, wave dynamics, and responsive buoyancy are important. Designed for flexibility and scalability, DRW fits both small-scale scenes and large open environments.
