Technical Details


Features

  1. Niagara two-way data flow: drive particles using fluidsim / drive fluidsim using particles
  2. Local solver combined with pattern generators to render infinite fields of responsive sand, water, fog
  3. Cinematics: ready for rendering via Movie Render Queue, supports Sequencer
  4. Volumetrics: custom, lit 3D Smoke volume included + driving native UE Fog and Clouds
  5. Scalable: could be optimized for mobile devices or run a 4k sim container
  6. Simple-mode: track objects and draw trajectories without running fluidsim (eg. footsteps)
  7. Modular: could be added as ActorComponent / could drive other components (niagara, volumes)
  8. Sim buffers exposed (density, velocity, pressure)
  9. Examples included (20+ tutorial levels, 10+ usecase levels)
  10. Compiling and packaging is tested on Windows, Apple and Android devices
