About the Celestia modpack
This pack provides client-side quality of life and enhancement mods to be used with a Fabric server with server-side mods for a close to vanilla experience.
The pack enhances the game with preconfigured shaders, quality of life tweaks such as AppleSkin and BetterF3, ambient sound effects, controller support, reacharound placement, inventory sorting, a hotkey to the wiki using Hey Wiki and more!
The pack also includes custom menus using FancyMenu to improve the user experience. This can be disabled with Ctrl+Alt+C. It is not recommended to use this pack on public vanilla servers as there is a risk of being banned because of some of these client-side mods, such as InvMove and Reacharound Placement.
You may check the Dependencies of each version for a full list of mods and features included in this pack.
