About Flex
Flex, developed by Zack Lovatt, provides tools for arranging layers in dynamically updating layouts within After Effects. It includes a Grid Mode that creates grid rigs and a Line Mode with Row and Column options for linear arrangements. Gutter controls let users set pixel‑precise spacing between layers. The plugin is at version 1.1.3, last updated in June 2022, and is compatible with After Effects releases from CC 2015.3 up to the 2026 version. Recent fixes address expression errors on source‑less layers and Grid Mode errors when using the legacy engine. In the current build, Matte Mode and inner/outer shape layer stroke options are disabled. A demo video is available on the developer’s site.
