Fluid is a GPU‑accelerated 2D fluid simulation plugin for After Effects that uses Navier‑Stokes physics to turn any alpha‑based layer into a fluid emitter with colliders, dual‑stream color blending and real‑time timeline playback.
Developed by YCraft.

About Fluid
Fluid is a GPU‑accelerated 2D fluid simulation plugin for After Effects built on Navier‑Stokes physics. It reads an alpha layer’s shape and emits fluid along the exact contour, allowing logos, text and graphics to flow naturally. The simulation evolves frame‑by‑frame with gravity, wind, buoyancy, vorticity and turbulence, and any alpha‑based layer can act as a collider with bounce and friction settings; invisible colliders can define hidden boundaries. A second independent emitter provides dual‑stream collisions with separate color control. Source Point keyframes can be generated by pasting mask paths for curved flow animations. The plugin runs live in the After Effects timeline without pre‑rendering, offering Standard, High, Ultra and Extreme quality levels that remain resolution‑independent across composition sizes. Fluid is compatible with After Effects 2021‑2026 on Windows 10/11 (OpenCL 1.2‑capable GPU) and macOS 11 Big Sur or newer (Metal‑capable GPU on Apple Silicon or Intel), requiring a minimum of 8 GB RAM, with 16 GB or more recommended for large compositions.
Features
- GPU-accelerated real-time Navier-Stokes simulation that runs live in the After Effects timeline, with no pre-rendering or external pipeline
- Any alpha-based layer becomes a fluid emitter, releasing fluid along the layer’s exact contour for logos, text, or graphics
- Second independent emitter for dual-stream collisions with per-source color control
- Collider layer support with Bounce and Friction, plus invisible colliders for hidden boundaries
- Mask path pasted as Source Point keyframes for organic, curved flow animations
- Physics controls including Gravity, Wind X/Y, Buoyancy, Vorticity, Swirl, and Viscosity, with 3-octave fBm turbulence and Wiggle
- Five color modes and post-processing with pseudo-volumetric Shading and Bloom, across Standard, High, Ultra, and Extreme quality levels
Best for
After Effects artists generating 2D fluid effects from layers such as logos, text, and graphics, including logo reveal and text dissolve workflows.
Frequently asked questions
Which After Effects versions does Fluid support?
