Fluid Flux
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 for foam, caustics, and waves
Water cross-section rendering
Limitations:
A detailed list of limitations can be found in the documentation [Documentation]
open-world is currently not supported
simulation can't be replicated
simulation is calculated in a 2d grid projected on the heightfield (captured ground)
system cant simulate wave breaks and splashing water
VR and mobile are not supported
currently non-tesselated plane mesh for rendering fluid surface
there is no integration with Water Plugin for now
