The system can handle underlying terrain slopes, arbitrary water depth, and supports wet-dry region tracking.
Here's a great new tool that will help you easily set up water in your Unreal Engine-powered project. Meet Fluid Flux, a powerful water system based on 2D shallow-water fluid simulations created by Game Developer and Programmer Krystian Komisarek. Fluid Flux can handle underlying terrain slopes, arbitrary water depth, and supports wet-dry region tracking. The system works in real-time and can be run on both UE4 and UE5.
Features:
- Realtime shallow water simulation – fluid data modifiers, wave generator, and extendable interface
- Fluid surface rendering – caustics, wetness, underwater, waterline, advected foam, advected waves, blending with the ocean, dynamic audio detection
- Fluid Interaction – simple cheap ripple solver moving with character, optimized to an absolute minimum
- Ocean wave blending – rendering tillable ocean heightmap texture in a single pass
- Niagara environment interaction – High-quality effects, bouncy, plants, character swimming, boats,
- Clean, efficient, GPU friendly implementation, interface designed with the KISS (Keep It Simple, Stupid) rule in mind
- Small, compact, and low memory footprint
- Tool for generating ultra-fast static meshes with flow maps baked into vertex color.
- Advanced fluid state management, loading state in gameplay.
- Niagara fluid async readback system for sampling height and flow of fluid in blueprints.
- Dynamic audio analyzer. The sound source is positioned based on fluid movement.
- Four example maps – beach, island, river, and baked static river
- Uses velocity based fluid flow advection method used for foam caustics and waves
Solo Developer Devon, who is currently working on a 3rd-person, open-world RPG called Elements, has already tried this system and used it for the game. Here's a demonstration:
