Aescripts - Fluid v1.0.0

Fluid
Fluid is a GPU-accelerated 2D fluid simulation plugin for After Effects. Built on real Navier-Stokes physics, it turns any layer into a fluid emitter with collider interaction, dual-stream color blending, and cinematic post-processing — all real-time*, directly in the timeline. Available on Windows and macOS.

REAL-TIME* 2D FLUID SIMULATIONS
Fluid is a GPU-accelerated 2D fluid simulation plugin for After Effects. Built on real Navier-Stokes physics, it turns any layer into a fluid emitter with collider interaction, dual-stream color blending, and cinematic post-processing — all real-time, directly in the timeline. Available on Windows and macOS.
SOURCE LAYER
Turn any layer in your composition into a fluid emitter. The plugin reads the layer's alpha shape and releases fluid along its exact contour, making logos, text, and graphics flow naturally.
Fluid behaves like a true fluid rather than a simulated effect. Gravity, wind, buoyancy, vorticity, and turbulence work together to shape the motion, while every frame evolves naturally from the previous one, producing authentic and continuously changing flow.

COLLISION
Any layer can be used as a collider. Fluid reads its alpha shape and interacts naturally with the surface, while Bounce and Friction shape the response. Invisible colliders let you guide the flow with hidden boundaries.

Keyframe the Source Point and Fluid automatically reads its motion, converting it into emission velocity for natural path-following trails. Tail Length, Velocity Dissipation, Front Bombe, and Wake Width dynamically react to the movement, producing stronger bursts and wider trails as the source speeds up.

DETAIL LEVELS
Choose between Standard, High, Ultra, and Extreme quality. Higher settings produce sharper detail and more refined motion, while lower settings keep previews fast and responsive.

KEY FEATURES
GPU-accelerated real-time Navier-Stokes simulation — runs live in the After Effects timeline, no pre-rendering or external pipeline required

Any layer becomes a fluid emitter — use logos, text, or graphics as fluid sources (logo reveal, text dissolve workflows)

Second independent emitter — create dual-stream collisions with per-source color control

Collider layer support — any alpha-based layer blocks the flow, with Bounce and Friction (Navier slip)

Mask path → Source Point keyframes — paste any mask path as keyframes for organic, curved flow animations

5 color modes — Original, Color, Dual Color, Random Color, Gradient — with per-source palettes

Full physics controls — Gravity, Wind X/Y, Buoyancy, Vorticity, Swirl, Viscosity

Procedural turbulence — 3-octave fBm noise plus Wiggle for natural motion variety

Post-processing — pseudo-volumetric Shading and Bloom with threshold control

4 quality levels — Standard, High, Ultra, Extreme — design fast, render sharp

Resolution-independent simulation — physics identical across all composition sizes
