Modern UI Mod FAQ
10 questions players actually ask, answered.
How do I open the Modern UI settings menu?
Open the standard Minecraft Options screen and look for the Modern UI button, or use the mod's own keybind if one is assigned in Controls. From there you can reach the dedicated settings page with all font, background, and window options.
How do I change the font in Modern UI?
Go to the Modern UI settings page and open the font section, then point it at a TrueType or OpenType font file. The preview updates in real time, and you can reload fonts without restarting the game.
How do I use emoji in chat with Modern UI?
Type the shortcode for the emoji you want in the chat box, and Modern UI renders it as the full Unicode 15.1 emoji. The mod supports the full emoji set, so any standard shortcode should work.
How do I enable background blur and change the screen background color?
In the Modern UI settings, find the background options and enable the Gaussian blur toggle, then pick a custom background color with the color picker. Both apply to menus and screens across the game.
How do I turn on borderless fullscreen?
Open the Modern UI window settings and switch the window mode to borderless fullscreen or maximized borderless. This removes the window border and lets the game fill the screen without the usual fullscreen toggle.
How do I limit the framerate when the game window isn't focused?
Enable the framerate limiting option in Modern UI's settings so the game caps FPS while the window is in the background. This reduces resource usage when you tab away without affecting performance while playing.
How do I make the game pause when I open my inventory?
Turn on the pause-on-inventory option in the Modern UI settings. With it enabled, opening your inventory in single-player pauses the game instead of letting the world keep running.
How do I change the GUI scale more precisely?
Modern UI replaces the vanilla GUI scale button with a slider, so you can drag it to any value instead of picking from fixed steps. Adjust it in the Modern UI settings or the standard video options where the slider appears.
Why is my custom font not showing up or looking wrong?
Make sure the font file is a valid TrueType or OpenType font and that you selected it in the font settings, then reload fonts. If text looks blurry or misaligned, try a different font size or check that the font supports the characters you're using.
Does Modern UI work with other mods and does it hurt performance?
Modern UI is designed to work alongside most mods, though mods that heavily customize their own GUI may not fully inherit the new style. Performance impact is generally small, but the Gaussian blur effect can cost some FPS on weaker systems, so disable it if you notice a drop.
