This is where the is a lifesaver. It's a specialized automation tool for After Effects that creates a complete, independent duplicate of a composition's entire hierarchy. It doesn't just copy the top-level comp; it duplicates every single nested pre-comp, footage item, and solid layer within it, creating a totally separate project branch. Once duplicated, you can freely modify the new comp or any of its newly created sub-comps without affecting the original project in any way.

: Automatically updating expressions so they point to the new duplicated layers instead of the originals.

If a composition is used multiple times, the script only duplicates it once, and all references point to the new copy, preventing unnecessary clutter.

If you're struggling to install the script, let me know which version of After Effects you're using (e.g., CC 2024, CC 2025). Share public link
