Get the Best Look From the Anime GUI With GUI Scale and Other Packs

The pack's character art and colorful accents are part of the menu textures. How sharp and readable they look depends on your interface settings and on what other packs you run.

Adjust GUI scale

1. Open Options > Video Settings.

2. Find GUI Scale and try each setting while a chest or your inventory is open in the background, or reopen one after each change.

3. A larger scale makes the artwork easier to see. A smaller scale leaves more of the world visible around the menu.

4. If the art looks cut off or cramped at Auto, try a fixed scale one step lower.

Running it with texture packs and shaders

• Block and item texture packs: These can usually run alongside the GUI pack. Put the Demon Slayer GUI Pack at the top of the Selected list so its menus are not replaced by GUI files inside the texture pack.
• Shaders: Shaders need a loader such as Iris or OptiFine. They change world lighting, not menu screens, so the themed menus should look the same with or without them. Load shaders through your loader's menu as usual and keep this pack enabled in Resource Packs.
• Check after changes: After adding or reordering any pack, open your inventory, a crafting table and a villager trade window. If all three still show the themed design, your setup is working.
