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:

[Documentation] Please read the description about limitations before purchasing. 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
