Atmosphere Menu

Atmosphere Menu gives Minecraft a customizable main menu with scenic backgrounds, smooth animations, clean typography, and a built-in clock.

Choose one of five bundled landscapes or add your own image or animated GIF. Subtle background movement and smooth transitions bring the menu to life, while the layout editor lets you arrange its elements to suit your setup.

Features

• Scenic backgrounds with optional motion, mouse parallax, and animated switching.
• Custom PNG, JPG, and GIF backgrounds, including drag-and-drop import.
• A clock, date, and personalized greeting.
• A layout editor for moving, resizing, and hiding menu elements. Hold Shift to move freely, use the mouse wheel to resize, and press Del to hide an element. Ctrl+E opens the editor; R restores the default layout.
• Consistent styling for buttons, sliders, text fields, settings screens, and the pause menu.
• Smooth opening and closing animations for inventory, chat, and the Tab player list.
• An account manager for local profiles and Microsoft accounts, with search, pinned profiles, and skin and cape previews.
• Three saved-account storage choices: password protection, device-bound protection, or unencrypted storage with a warning.
• Localized menus, with Minecraft's standard font used for scripts outside the bundled font's coverage.
• A standard-menu mode, accessible with M, that uses resource-pack GUI textures and fonts and shows third-party menu buttons.

The custom main menu hides buttons added by other mods. Switch to standard mode with M to access them. Resource-pack textures for the game world, blocks, and items continue to work in custom mode. Compatibility with every third-party screen replacement is not guaranteed.

Installation

Atmosphere Menu is a client-side Fabric mod for Minecraft Java 1.21.4 and 1.21.11. Download the file matching your Minecraft version and place it in your mods folder. Use only one Atmosphere Menu JAR at a time.

• Minecraft 1.21.4: Fabric Loader 0.16.9 or newer and Java 21.
• Minecraft 1.21.11: Fabric Loader 0.19.5 or newer and Java 21.

The required Fabric API modules and In-Game Account Switcher 9.0.8 are included as nested dependencies. No separate installation is needed. If your modpack already includes IAS, use a compatible 9.0.8 release for the same Minecraft version.

Microsoft sign-in takes place in your browser through In-Game Account Switcher. You need an account that owns Minecraft Java Edition. Local profiles use offline authentication and do not grant a Minecraft license or access to online-mode servers. Leave your world or server before switching accounts.

Never share the _IAS_ACCOUNTS_DO_NOT_SEND_TO_ANYONE folder from your game directory. Account protection does not protect an active session from malware on the same computer.
