About Keystone 3

Keystone 3 is a toolset for After Effects from Romain Cousin, built for animators. It consolidates functions for aligning, staggering, ordering, stretching layers, and applying color labels into one panel. The stagger tools include Bezier controllers, three calculation methods and a cumulative mode. Additional sections let users edit keyframe values, control layer order, and quickly move between controls with shortcuts. The Anchor section can reposition anchor points or create null objects via CTRL/CMD click, targeting individual layers, groups, the composition, custom coordinates, or internal anchors of shape and text layers. Null layers generated by the Anchor functions are placed directly above selected layers and trimmed to match the length of their children. Version 3.1.4 works with After Effects 2026, 2025, 2024, 2023 and 2022.
