FluidNinja LIVE

Fast, responsive Fluid Simulation for Character and Environment VFX: sea, rivers, clouds, smoke, fire, sand, snow and foliage. Drive all dynamic systems with fluidsim.

Welcome to NinjaLive 1.9.54.4: modular fluidsim for UE 5.1 - 5.4 that could be used for screen-space effects

and drive world-space systems: water bodies, volumes, niagara, foliage and landscape components.

PLEASE NOTE: NINJA IS NOT A DRAG-N-DROP TOOL, LEARNING IT TAKES A WEEK.

Technical Details

Features

1. Robust: capable to track hundreds of objects and bones - including Metahuman skeletons
2. Large scale: local fluid solver extended with global pattern generators - to render infinite fields of sand, water, fog
3. Large distances: unreal Large World Coordinates (LWC) are supported
4. Volumetrics: supporting all native UE Volume types: Fog, Clouds and Heterogeneous Volumes
5. Simple-mode: track objects and draw trajectories without running fluidsim (eg. footsteps, wheeltracks)
6. Scalable: could be optimized for low-end hardware or run a 4k sim container
7. Modular: could be added as ActorComponent / could drive other components (niagara, volumes)
8. Niagara: two-way data flow - drive particles using fluidsim / drive fluidsim using particles
9. Sim buffers (density, velocity, pressure) exposed to RenderTargets
10. Cinematics: ready for rendering via Movie Render Queue, supports Sequencer
11. Examples included (30 tutorial levels, 20 use case levels)
12. Compiling and packaging is tested on Windows and Android devices
13. Important: NINJA IS NOT REPLICATED, MULTIPLAYER IS NOT SUPPORTED
