Butterium is a feature-packed and user-friendly way to experience Minecraft without performance issues or a billion ugly configuration screens. Our **fine selection of performance mods and configurations** allows for your game to run **_smooth like butter_** on even the weakest hardware and devices. It's designed so that anyone— no matter if they're new to the game or already a pro PvP player— can enjoy the game _smoothly_, **without interruptions** with all the features and mods they like We at BUTR Studios achieve lots of this by **integrating** each mod into **our very own custom-made ButterUI**. So, to put it simply, we achieve UX _perfection_ with **performance, quality of life and gameplay** all in one pack with **~42 mods.** **Please view [the gallery](https://modrinth.com/modpack/butterium/gallery) to see more** UI, HUD and features ![ButterUI Title Showcase](https://github.com/BUTR-Studios/Modpacks/blob/Butterium-dev/.github/ASSETS/butterui-showcase.webp?raw=true) > ↳ _Mid-resolution gif of ButterUI customizations minimized to a small window_ ## Features for days

⚡ **Lightning fast performance** - Despite its large feature set, Butterium has comparable and sometimes better performance than the top performance packs and clients without being a bloated RAM hog _(especially in multiplayer)_

🎮 **Cool Gameplay/Multiplayer Features** - We have integrated mods for **freecam, fullbright, version-switching/spoofing, account switching, resource/shader pack browsing, voice chat** and more to ensure that you have **more than just _smooth_ frame rates** and nice GUI's

⚙️ **Custom Settings and GUI's** - We use FancyMenu to **fine-tune** our GUIs and **integrate** mods **using our own ButterUI design language**, integrated mods feature redesigned config screens accessible from Butterium menus and settings

🎮 **Custom HUD** - We integrate features like keystrokes, time, armor display, co-ordinates and more into Butterium's HUD, you can drag everything around with ease

📆 **Regular Updates** - BUTR Studios is dedicated to meeting user needs by **adding new features**, bug squashing and improving UX with every update

ButterUI is an OreUI-inspired design language featuring **user-friendly, abstract-looking menus** and **insane** customisation - you can simply change the **accent color and background** from our nice personalisation menu > ↳ Or you could even enter FancyMenu (please read [the documentation](https://docs.fancymenu.net/)) and customise **EVERYTHING**- Not _easy_ but still super cool for advanced users We provide ButterUI support for a whole bunch of mods- all included mods should be supported and a range of popular mods you can add yourself are supported to be consistent with ButterUI design. A list will be released soon on GitHub The ButterUI experience is created using our own resources and FancyMenu configuration. I (caela.uk) work with FancyMenu **a lot** and have been for approximately 2 years now. I commonly push FancyMenu's limits and have to request tons of features, most of which Keksuccino kindly adds for me (and others) to make ButterUI better with ## Why 'client'? It's a modpack?

We refer to Butterium as a **_Client-like_ modpack**. Lets explain **why**: 1) **Many** of our users have **switched** from using **popular clients to** using **Butterium** 2) Us devs make this pack feel as **custom made** for **you** as possible _(e.g **draggable window**s, **onboarding**)_ 3) We're working to make this pack **integrate each mod** to **_perfection_**, from **custom menus**, **keybinds** and **commands**, to completely **custom mods** themselves _(coming soon)_ 4) We are actively working on a client-like yet minimal launcher with the ability download and install the modpack from Modrinth automatically for those users who might be new to modpacks or transitioning from a popular client or vanilla

Most, if not all of our GUI's were created using the **amazing tool** that is **[FancyMenu](https://modrinth.com/mod/fancymenu) by [Keksuccino](https://modrinth.com/user/Keksuccino)**, this is amazing for creators as it allows for **custom** designs and scripting within Minecraft, faster and better than any custom mod we could ever create ourselves Butterium has been a passion project of many names over the past 2 years and we wouldn't be here if not for our amazing community and supporters from the Minecraft modding scene We protect our work here with the [Smooth Like BUTR Licence](https://github.com/BUTR-Studios/Modpacks/blob/Butterium/LICENCE.md)
