What It Does
Property Effector links multiple layer properties to a unified set of animation controls. Instead of animating each property separately, you create one driver that controls everything. The tool uses expressions behind the scenes, but you never write code yourself.
Key Features
Unified driver control. Create a single effector driver that controls multiple properties across layers. Animate the driver once, and all linked properties respond according to their individual relationships.
Cross-composition support. Absolute effectors let you control animations across different compositions and pre-comps from one location. Useful when managing complex project structures.
Flexible relationships. Fine-tune how much each property responds to the driver. One property might move 100% when the driver changes, another 50%, another in the opposite direction. These relationships define the animation’s character.
Works with third-party plugins. The effector system works with particle systems like Trapcode Particular, audio-reactive setups, and most After Effects plugins. If it has animatable properties, you can link it.
Driver limits. Restrict drivers to positive or negative values only, preventing unwanted animation ranges. Add as many effectors as needed to a single composition.
Easy removal. Effectors can be removed cleanly when you need to adjust your setup or revert to manual keyframing.
Who It’s For
Motion designers working with complex rigs benefit most. If you’re animating character systems, mechanical objects with multiple moving parts, or data visualizations with synchronized elements, Property Effector reduces repetitive keyframing. The audio visualizer tutorial demonstrates typical usage: linking particle properties to audio amplitude so everything responds together.
The tool fits projects where timing relationships matter more than absolute values. Instead of copying keyframes across properties and adjusting their timing curves, you define the relationships once and animate the driver.
