Reacto
A smarter, more responsive way to animate motion.
Reacto is a behavior-driven animation system for After Effects that transforms movement into dynamic reaction. Instead of offsetting keyframes, it interprets motion energy and distributes natural, controllable responses across connected layers — giving you fluid, intelligent animation without complex setups.
Driver-Based Motion System
Animate once. React everywhere.
Reacto uses a central driver layer to generate motion responses across selected followers. Move one layer and watch the rest react dynamically — no manual offsetting, no copy-paste keyframes.
Velocity-Aware
Reactions
Motion that responds to energy.
Reacto doesn’t delay keyframes — it reads movement speed and direction, generating intelligent reactions based on motion intensity. Faster movement creates stronger responses. Slow movement settles naturally.
Behavior-Level Randomisation
Organic variation without chaos.
Built-in randomisation adds controlled variation across followers — perfect for flags, crowds, UI elements, secondary motion, and complex rigs that need natural imperfection.
Puppet-to-Null Rig Builder
Rig smarter. Animate faster.
Automatically convert puppet pins or selected hierarchies into a structured null-based control system. Reacto builds the setup so you can focus purely on animation.
3D Layer Support
Reactive motion across true 3D space.
Reacto works seamlessly with After Effects 3D layers, allowing motion reactions to propagate through depth as well as position. Animate drivers in 3D and followers respond naturally across X, Y, and Z space — ideal for spatial rigs, layered scenes, and camera-driven animation.
