Project Builder Lite is an add-on that generates structured project folders and saves .blend files through automated, customizable presets. The add-on creates folder trees tailored for assets, caches, renders, and exports based on plain text files, eliminating the need to manually construct directories for every new project. It offers multiple saving methods, including copying the current file, creating a clean file, or copying a template setup.

Additionally, the add-on includes a payload system that can automatically copy files, directories, or extract ZIP contents into the new project infrastructure. This allows for rapid distribution of reference materials, HDRIs, or base textures. The tool can also trigger post-build actions like launching external programs, running scripts, or opening specific directories once the project is initialized.
