OptiGUI

# OptiGUI [](https://github.com/opekope2/OptiGUI/releases) [](https://modrinth.com/mod/optigui/versions) [](https://www.curseforge.com/minecraft/mc-mods/optigui/files) [](https://github.com/opekope2/OptiGUI/stargazers)  [](https://opekope2.dev/OptiGUI) [](https://ko-fi.com/opekope2) OptiGUI is a client-side mod, which enables the customization of in-game GUI screen textures with resource packs. Now rewritten from scratch in Kotlin for cleaner code, better performance, more features, and extensibility. Other mods' developers can add their custom containers and customization options. See documentation link above. [Supports most OptiFine GUI resource packs](#supported-resource-packs). If a resource pack does not work or works differently than using OptiFine, please open an issue (select the **Report a bug** template). Check out my new OptiGUI resource pack for Minecraft 1.19+: [Chest Boat GUI](https://modrinth.com/resourcepack/chest-boat-gui) ⚠️ OptiGUI 2.3.x prior to beta 8 is incompatible with Fabric Language Kotlin 1.13.5+. Please downgrade to Fabric Language Kotlin 1.13.4. [](https://bisecthosting.com/opekope2) ## How to use it ⚠️ If you're not a resource pack creator experimenting with [OptiGUI 3 JSON resources](https://opekope2.dev/OptiGUI/JSON.html), then you should stick with OptiGUI 2.3.x betas. 1. Download and install [Fabric loader](https://fabricmc.net/use) or [Quilt loader](https://quiltmc.org/en/install) 2. Download this mod to your mods folder 3. Download the required dependencies to your mods folder as well 4. Download and enable a supported resource pack (see below) ## Supported languages * 🇺🇸 by [opekope2](https://github.com/opekope2) * 🇹🇼 by [dirtTW](https://github.com/yichifauzi), [notlin4](https://github.com/notlin4) * 🇨🇳 by [dirtTW](https://github.com/yichifauzi), [notlin4](https://github.com/notlin4) * 🇩🇪 by [Lucanoria](https://github.com/Lucanoria) * 🇪🇸 by [LyriaWintona](https://github.com/LyriaWintona) * 🇮🇹 by [RoberbufDx8105](https://github.com/RoberbufDx8105) * 🇲🇾 by [NuruddinPlays](https://github.com/NuruddinPlays) * 🇺🇦 by [gorr0w7](https://github.com/gorr0w7) Want to see your name here? [Translate OptiGUI to your native language](https://github.com/opekope2/OptiGUI/blob/dev/CONTRIBUTING.md#i-want-to-add-a-translation). ## Compatibility ### Cobblemon If you play with Cobblemon 1.5.2 and earlier, you need Fabric Language Kotlin [1.10.11+kotlin.1.9.20](https://modrinth.com/mod/fabric-language-kotlin/version/1.10.11+kotlin.1.9.20) or earlier (which doesn't crash). ### Supported loaders & clients As of the latest OptiGUI 3 alpha release, only Fabric & Quilt loaders are supported. ⚠️ Quilt support is based on Quilt loader's support for loading Fabric mods. ⚠️ Support for using Fabric compatibility layers or alternative clients such as Sinytra Connector or Lunar client is done on a best-effort basis, but [issues](https://github.com/Sinytra/Connector/issues/1403) [may](https://github.com/opekope2/OptiGUI/issues/114) [arise](https://github.com/opekope2/OptiGUI/issues/121), which is not necessarily OptiGUI's fault. ## Resource pack docs OptiGUI supports OptiFine custom GUI resource packs, and also supports OptiGUI resource packs. OptiGUI resource packs are more flexible than OptiFine resource packs. See documentation link above to get started. ## Supported resource packs (OptiGUI 2.3.x) Excluding vanilla resource packs (which don't container OptiFine or OptiGUI-specific files) * [Colourful Containers](https://www.planetminecraft.com/texture-pack/colourful-containers-gui/) * [Colourful Containers Add-On](https://www.planetminecraft.com/texture-pack/updated-colourful-containers-light-mode-gui-optifine-required/) * [Colourful Containers Dark Mode](https://www.planetminecraft.com/texture-pack/colourful-containers-dark-mode-gui-optifine-required/) * [Animated RGB GUI](https://www.curseforge.com/minecraft/texture-packs/optifine-animated-rgb-gui) ¹ * [NEON20 ANIMATED](https://www.planetminecraft.com/texture-pack/neon20-animated-optifine/) * [Rybo's Enhanced GUI](https://www.planetminecraft.com/texture-pack/rybo-s-enhanced-gui/) * [Animated Fox Guis](https://www.planetminecraft.com/texture-pack/animated-fox-guis-1-16-x/) ¹ * [\[DARK\] Animated Fox Guis](https://www.planetminecraft.com/texture-pack/fox-4931933/) ¹ * [Recolourful Containers GUI + HUD](https://www.curseforge.com/minecraft/texture-packs/recolourful-containers-gui-hud) ¹ see FAQ for animation support This list is not exhaustive. If you know a resource pack which works, and you'd like to see it here, or a resource pack, which does not work, but works with OptiFine, please open an issue. ## Partially supported resource packs Excluding vanilla resource packs (which don't container OptiFine or OptiGUI-specific files) * [New Default+](https://www.curseforge.com/minecraft/texture-packs/newdefaultplus) ¹ ¹ Barrel does not work, neither does it work with OptiFine. The resource pack does not specify it according to the format. ## FAQ ### Use in a modpack? Yes. ### OptiFine GUI animations? Only with [Animatica](https://modrinth.com/mod/animatica). ### OptiFine colors (colors.properties)? No, use [Colormatic](https://modrinth.com/mod/colormatic). ### Performance impact? OptiGUI's performance impact is negligible (tho it varies a bit depending on which resource packs are used). ### Configuration GUI/file? Nothing to configure. ### Sodium? Yes. ### OptiFine? Actually, OptiGUI and OptiFine (with OptiFabric) **can** be loaded simultaneously. I have observed that OptiGUI mixins will be placed before OptiFine ones, so you can turn off custom GUIs in OptiFine to save performance. However, I can't assist you with this.
