Dynamic App Icon Mod FAQ
10 questions players actually ask, answered.
How do I set up an icon for my world?
Place a PNG image file in your mod's config folder with a name matching your world folder name, then rejoin that world—the mod will automatically detect and apply it as your app icon.
What image format and size should my custom icon be?
Use PNG format; the mod works best with square images, typically 256×256 pixels or larger, though smaller sizes will scale automatically.
Why isn't my icon changing when I join a world?
Check that your PNG filename exactly matches your world folder name (case-sensitive on some systems), that the file is in the correct config directory, and that you've fully loaded into the world before expecting the change.
Can I use different icons for servers vs. single-player worlds?
Yes—name server icons after the server address or use the server's display name in your config, and single-player icons after world folder names; the mod distinguishes between them automatically.
Does this mod work with server resource packs or mods that change textures?
The mod only controls the application window icon and doesn't interact with in-game textures or resource packs, so it's fully compatible with any texture or content mods.
Will this mod affect my game performance or FPS?
No—the mod only updates the app icon when you join a world or server, which has negligible performance impact and doesn't run during gameplay.
Can I set a default icon that appears when I'm in the main menu?
Yes—create a default or fallback icon file in the mod's config folder (check the mod's documentation for the exact filename convention) to display when no world-specific icon is active.
What happens if I delete or move a world—does the icon disappear?
The icon file remains in your config folder independently; if you want to remove it, you'll need to manually delete the PNG file from the mod's directory.
Does this work with modpacks or custom launchers?
The mod works with any launcher that runs standard Minecraft, though some launchers may cache the app icon—restarting the launcher usually forces it to refresh.
Can I use animated GIFs or video files as icons?
No—the mod only supports static PNG images; animated formats are not supported by the application icon system.
