About Loop Tools Pro

Loop Tools Pro is a script for Adobe After Effects that applies multiple non‑destructive loop cycles to a single layer property. Loops are driven by a “Super‑Expression” linked to LOOP_START and LOOP_END markers, so original keyframes remain unchanged. The tool supports Position, Scale, Rotation, Opacity, Path and other common properties. Users can create several unique loops on one property and apply them across dozens of selected layers with multi‑layer support. Loop ranges can be auto‑detected from selected keyframes or set manually via UI sliders, and a Smart Rebake function smooths transitions for seamless loop exits. A “Delete Loops” button removes all script‑generated markers and expressions, resetting the layer while preserving original animation. The dockable UI panel works with After Effects versions from CS6 through 2026, using matchNames for language‑independent compatibility.

Features

• Non-destructive workflow: original keyframes stay untouched, with loops driven by a “Super-Expression” tied to LOOP_START and LOOP_END markers
• Multiple unique loop cycles on a single layer property
• Multi-layer support to apply loops, rebake keyframes, or delete expressions across dozens of selected layers at once
• Smart Rebake corrects transitions to help ensure a seamless loop exit
• Auto and manual ranges: auto-detect selected keyframes or set start/end frames with UI sliders
• “Delete Loops” button removes all script-generated markers and expressions to reset
• Works with Position, Scale, Rotation, Opacity, Path, and more

Best for

After Effects animators who need to add and manage repeating loop cycles on layer properties without modifying the original keyframes.
