\n## What does this pack do?<\/p>\n
Butterium is a **client-like modpack** that makes your game _**as smooth as possible**_ by *(in some cases)* **QUADRUPLING your FPS** allowing for **smooth** gameplay on **even the lowest of hardware**. In some cases this pack **even performs better than both Lunar and Feather**<\/p>\n
Butterium also **integrates** each mod into **it’s very own custom-made ButterUI** so you **shouldn’t ever see an ugly config file or bloated menu** with thousands of options **ever again**<\/p>\n
To put it simply, we achieve UX *perfection* with **performance, quality of life and gameplay** all in one pack with **less than 36 mods**.<\/p>\n

## Features<\/p>\n
\u26a1 **Lightning fast performance** – Butterium has comparable performance to the top performance packs on this platform without being a bloated RAM hog, in *some* cases we **out-perform these packs** *(especially in multiplayer)*<\/p>\n

<\/p>\n
## What is ButterUI?
\nButterUI 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 a nice personalisation settings menu
\n> \u21b3 Or you could even enter FancyMenu (please read the documentation) and customise **EVERYTHING**- Not *easy* but still super cool for advanced users<\/p>\n
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<\/p>\n
ButterUI is made with our own resource packs 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<\/p>\n
## Why is this modpack to be compared to a client?<\/p>\n
As you can see, we refer to **Butterium as a *Client-like* modpack**. Lets explain **why**:<\/p>\n
1) **Many** of our users have **switched** from using **popular clients to** using **Butterium**<\/p>\n
2) Us devs make this pack feel as **custom made** for **you** as possible _(e.g **draggable window**s, **onboarding**)_<\/p>\n
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)*<\/p>\n
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<\/p>\n – [x] Add a “support us” widget<\/p>\n – [ ] ButterHost integration and features – [ ] Installer, launcher and minimal mobile app – [ ] Launcher Crash Assistant – [ ] Redesign HUD editor w\/ support for resizable HUD widgets – [ ] Optional translucent HUD widget backgrounds<\/p>\n – [ ] Set up Discord Status to include download button<\/p>\n – [ ] For cool events servers, show live events on a main menu widget<\/p>\n – [x] Move assets to resources > Rework all icons as pixel-perfect images (maybe with seperate folder for included shadows)<\/p>\n > Move all text to localization keys<\/p>\n – [ ] Spec detection and optimization > Hardware scoring system, then finds optimal configs and modset for your specs<\/p>\n – [ ] Screenshot previews and viewer<\/p>\n – [ ] Elimination counter > credit: fishandchips<\/p>\n – [ ] Custom HUD item counters > credit: fishandchips<\/p>\n – [x] Armor and tool durability notifications – [ ] Ports to 1.21.1 and 1.20.1 Fabric, maybe NeoForge one day<\/p>\n – [ ] Allow compatible mods to be installed and toggled from in-game > Remove mods with .bat\/.sh<\/p>\n > Inspired by Lunar and Feather mods screens- showing just icons, clicking them opens the description and\/or config (maybe a description screen with a button for config)<\/p>\n – [ ] Update and enable friends sidebar – [ ] Click FX at the cursor – [ ] Donate, help and Discord buttons somewhere in options<\/p>\n – [ ] Fix variable names and values + simplify and optimize all layouts and element anchors – [ ] Known mod incompatibility warning from GitHub (ver).txt > Possibly also “compatibility mode”<\/p>\n – [ ] Custom inventory shortcuts – [x] Remove some layouts for settings menus – [ ] Send specs to API on command using MC username for help support – [ ] Advanced customisation button in personalisation and Credits menus that leads to new menu – [ ] Custom backgrounds replacing “0” in the BG carousel (.png, .jpg, .jpeg)<\/p>\n – [ ] Light and Midnight UI themes – [x] Use the accent colour in more places and improve UI design<\/p>\n – [ ] Tools for resource pack creators – [ ] Toggleable health indicators ## Credits\/Legal<\/p>\n Most, if not all of our GUI’s were created using the **amazing tool** that is **FancyMenu by Keksuccino**, this is amazing for modpack creators as it allows for **custom** designs and scripting within Minecraft<\/p>\n **Some** optimization mod config files were taken\/tweaked from Simply Optimized, but **not tooo many**<\/p>\n 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<\/p>\n We protect our work with the Smooth Like BUTR Licence (SLBLv1)<\/p>\n ## Where do I report bugs\/request features?<\/p>\n If you encounter any **incompatibilities, missing features or bugs** whilst using this modpack please report them to the BUTR Studios official Discord linked below **\u2193**<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Optimization\/FPS and quality of life.

\n> \u21b3 Like controlling the server and starting a free trial from in game *(referral systems too)*, hook in with the social features<\/p>\n
\n> \u21b3 https:\/\/github.com\/BUTR-Studios\/BUTR-Launcher<\/p>\n
\n> \u21b3 With Discord link and “copy logs” button<\/p>\n
\n> \u21b3 With sliders and submenus<\/p>\n
\n> \u21b3 Also allow resource pack to edit configs and stuff with txts like overrides (prompt first)<\/p>\n
\n> \u21b3 https:\/\/github.com\/BUTR-Studios\/spec-engine<\/p>\n
\n> \u21b3 Maybe similar to Fortnite- skull icon?<\/p>\n
\n> \u21b3 e.g. gapples, arrows, potions<\/p>\n
\n> \u21b3 credit: fishandchips<\/p>\n
\n> \u21b3 “You have unsaved changes” text for when the user needs to restart their game<\/p>\n
\n> \u21b3 With world\/server invites, friends sidebar and social features are currently half-finished<\/p>\n
\n> \u21b3 Cool, customizable effect that follows accent colour<\/p>\n
\n> \u21b3 This will help users better understand Butterium and edit the FM configuration<\/p>\n
\n> \u21b3 Compare loaded mods to a GitHub list of incompatible mods – also print to logs<\/p>\n
\n> \u21b3 Should be styled like the inventory and also adapt to resource packs, maybe contact some RP creators to add support<\/p>\n
\n> \u21b3 Would improve mod compatability with mods that change settings<\/p>\n
\n> \u21b3 Optionally also logs but we must ask for the users explicit permission and warn them of what logs store before doing anything<\/p>\n
\n> \u21b3 This menu should teach users how to create and download resource packs for Butterium<\/p>\n
\n> \u21b3 credit: fishandchips<\/p>\n
\n> \u21b3 W\/ FMv3.8 – imagine making a resource pack just by walking around your world and clicking blocks to change their texture by selecting a png from your system. This will update the pack you’re working on in real time but won’t **replace** messing with files<\/p>\n
\n> \u21b3 Could be done with a resource pack or mod
