Once the pack is active, it helps to know which screens you should expect to change. You can then spot quickly whether something is overriding it.
Screens to test in a world
1. Inventory: Press E. This is the main screen the pack replaces with its tech design.
2. Crafting table: Place and open one. The crafting screen uses the same unified style as the inventory.
3. Smoker: Place a smoker and right-click it. The pack includes a custom screen design for this block.
4. Loom: Open a loom to see its custom design. Pattern selection happens on this screen, so this is a good place to check readability.
5. Brewing stand: Open one to see the third custom block screen the pack adds.
A creative world is the fastest way to grab all of these blocks for a quick test.
Screens outside your world
- Advancements: Press L by default and look at a tab such as The End. It should show the same sleek, unified style.
- Options and menus: Every button should match the new theme.
- Text fields: Typing boxes, such as the world name field or an anvil's rename box, should share the clean look.
If a screen from this list still looks vanilla, another resource pack is probably sitting above AE2 GUI in your Selected list.
