AE2 GUI Resource Pack leaves blocks, items and animals untouched. That makes it a good partner for a texture pack that changes how your world looks. Done right, you get the AE2-style menus and your other pack's blocks at the same time.
Set the load order
In Minecraft, packs higher in the Selected list override packs below them wherever both change the same thing.
1. Open Options, then Resource Packs.
2. Move both AE2 GUI Resource Pack and your texture pack into the Selected list.
3. Use the up and down arrows on the pack icons to place AE2 GUI above the texture pack.
4.
This order works even if your texture pack has its own menu art. AE2 GUI wins on the interface, and your block pack still supplies everything in the world.
Test the combination
- Look around your world. Blocks, items and mobs should show your texture pack's style.
- Press E, then open a crafting table, smoker, loom and brewing stand. These should all use the AE2 design.
To use your texture pack's menus instead, move it above AE2 GUI. Some screens may then mix the two styles, depending on which screens each pack covers. Swap the order back if the menus end up looking mismatched.
