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