The Expression Engine - An After Effects Script

The Expression Engine – A Motion Wizard’s Toolkit for After Effects
Summon the power of expressions with a single click. Whether you’re animating a nebula, a dragon's wingbeat, or a sleek sci-fi HUD, The Expression Engine gives you precise control over your After Effects layer animations — without the dark arts of scripting.

Features worthy of the Galactic Federation:

• Apply wiggle(), random(), loopOut(), posterizeTime() and more
• Use dropdown spells (ahem, expressions) with real-time parameters
• Apply to selected transform properties across dimensions (X, Y, Z)
• Choose your method of insertion: Append, Prepend, or Replace
• Target specific axes — because not every rebellion starts on all fronts
• Enable Uniform Scale mode and override the timeline with ease
• Remove expressions with Jedi precision — either all or just selected

Made for Creators, Not Coders
Whether you’re an animation apprentice or a seasoned FX warlock, The Expression Engine lets you focus on timing, motion, and drama — not syntax errors.

1. Select one or more layers
