F1 Loading Screen V4 uses the f1-loading-screen-v4 resource folder and ensure f1-loading-screen-v4 in the original README. Its manifest points to index.html and includes js/config.js, js/main.js, CSS, images and audio files. Keep those paths intact when customizing the package.
Setup and checks
The manifest enables manual shutdown and loads main.lua. Check that the loading screen closes when joining finishes, then test music controls and missing-image behavior. A working browser preview alone does not prove that the FiveM connection transition works.
