This After Effects script thoroughly cleans your project by automatically removing all expressions from every layer and property within your compositions. It recursively scans through property groups, ensuring that even nested expressions are eliminated. With built-in error handling and detailed logging, the script not only reports the total number of expressions removed but also provides console output for any issues encountered during the process. Ideal for optimizing your projects and preparing them for further work, this tool streamlines the cleanup process, saving you time and effort.
