Everything you need to know about installing and using Luminex Client on Minecraft Fabric 1.21.11.
Luminex Client targets Minecraft 1.21.11 with Fabric Loader. No other loaders (Forge, NeoForge, etc.) or Minecraft versions are officially supported.
Yes. Luminex Client is completely free. No account, subscription, or payment is required. Download directly from the Downloads page.
1. Install Fabric Loader for Minecraft 1.21.11.
2. Download Fabric API for 1.21.11 and place it in .minecraft/mods.
3. Download the Luminex Client .jar and place it in the same mods folder.
4. Launch the Fabric 1.21.11 profile in your Minecraft launcher.
Press Right Shift after joining a world or server to open the Luminex Client module browser. You can search and toggle modules from there.
The most common causes: (1) wrong Fabric API version — make sure it matches 1.21.11, (2) launching the Vanilla profile instead of the Fabric profile, (3) missing Fabric Loader installation. Delete your mods folder contents and start fresh from the Downloads guide if issues persist.
Luminex Client runs entirely client-side and can be used on multiplayer servers. Always review a server's rules before using PvP mods — some servers prohibit client modifications.
Open the GUI with Right Shift, find the module you want, then right-click it and select Bind Key. Press the desired key when prompted.
Remove the old Luminex Client .jar from your mods folder and replace it with the new version downloaded from the Downloads page. Keep Fabric API up to date as well.
