Fluid Flux

The Fluid Flux is a powerful water system based on 2D shallow-water simulations.

Current Version 2.2

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, animated 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 fluid flow 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 for foam, caustics, and waves
• Water cross-section rendering
• Large-scale nonsimulated coastline(up to 10x10 km) with wave break based on wave profile technology
• Infinite mesh grid rendering based on Niagara
• Watercolor presents, advanced scattering settings, and brush painter
• Underwater based on SLW material mode working with changeable time-of-day

Limitations:

Please read the description about limitations before using. It is important!

• Open-world is currently not supported
• Multiplayer is not supported, and simulation can't be replicated
• Simulation is calculated in a 2D grid projected on the heightfield (captured ground)
• Wave breaks are not simulated. It's based on predefined wave profile animation
• VR and mobile are not supported
• There is no integration with the Water Plugin
