Before 26.1 they use the dragon's alpha pipeline, whose shader only samples the texture. entityCutout, which 26.1 used instead, applies the lightmap and directional shading, so shadows and light from the world showed on them. 26.1 builds the same unlit cutout from the entity shader: the emissive snippet without the lightmap, plus NO_CARDINAL_LIGHTING and NO_OVERLAY.

Saturn Client
A free and open-source Minecraft client.
Built with performance, customization, and community in mind.
About
Saturn Client is a free, open-source Minecraft client designed to enhance the gameplay experience while staying lightweight and customizable. Our goal is to build a clean, optimized client that the community can contribute to and improve together.
Saturn runs on Fabric and supports Minecraft 1.21.4 to 1.21.11 and 26.1, with one build per version (the 26.1 build also runs on 26.1.1 and 26.1.2). If something doesn't work on your version, please open an issue.
Features
- Free cosmetics that don't require real money: cloaks, including animated ones, and hats
- 18 built-in mods: Armor Display, Auto Sprint, Clock, Coordinates, Crosshair, Day Counter, FPS Display, Freelook, Fullbright, Health Display, Keystrokes, Nametags, No Fog, Ping Display, Speedometer, Status Effects, TPS Display and Zoom
- Clean and modern UI with animations
- Ongoing performance improvements
- Open-source and community-driven
Installation
- Install Fabric Loader and Fabric API for your Minecraft version.
- Download the Saturn Client jar for the same version from Modrinth or the releases page.
- Put it in your
modsfolder.
Network use
For cosmetics, Saturn Client connects to the Saturn server (saturn-server.selimaj.dev). You're signed in the same way as on an online-mode Minecraft server: your client proves who you are to Mojang's session server, and the Saturn server asks Mojang to confirm it. Your Minecraft access token is only ever sent to Mojang, never to the Saturn server.
Building from source
The version-independent code lives in the common submodule, so clone with submodules:
git clone --recurse-submodules https://git.selimaj.dev/saturnclientmc/saturnclient.git
cd saturnclient
./gradlew buildAll # every version → build/allJars/
./gradlew :1.21.11:build # a single version
./gradlew :1.21.11:runClient # launch a development client
Building needs Java 21. The 26.x versions compile with Java 25, which Gradle downloads when it isn't installed.
Contributing
We welcome contributions of all kinds:
- Code improvements
- Bug fixes
- UI enhancements
- Cosmetic designs
- Suggestions and feedback
If you're an artist or designer interested in helping with cosmetics or visual assets, we'd love to collaborate.
Most features belong in common, which every Minecraft version shares. For code that differs between versions, see the version guide: it covers how the versions share one copy of the code with Stonecutter, writing version-specific code, and adding a new Minecraft version. Every pull request is compiled for all versions automatically.
