Understand What Screens Are and Aren't Restyled by Apocalypse GUI
Covered Screens
Apocalypse GUI reskins the core vanilla menus: inventory, pause screen, hotbar, chests, crafting tables, enchantment tables, anvils, and beacons. It also updates custom interfaces from supported mods including Farmer's Delight cooking stations, Sophisticated Backpacks, TACZ weapon menus, Ultimate Car Mod vehicles, Curios equipment slots, and Furnish furniture menus.
Unsupported Screens
Mods not listed in the pack's compatibility will retain their original or default appearance. This includes less common mods, newly released mods, and niche content packs. The Apocalypse GUI wiki page lists all officially supported mods.
Extending Coverage
If you use mods that aren't covered, you have two options: search for alternative resource packs that target those specific mods, or create custom textures yourself using the pack's existing style as reference. The apocalyptic aesthetic is consistent enough that experienced players can sometimes match it manually.
