Full Brightness Toggle mod Troubleshooting
Why isn’t the Full Brightness Toggle mod working in Minecraft 2025?
Make sure you downloaded the correct version of the mod for Minecraft 1.21.5 and that it matches your mod loader (Forge, Fabric, NeoForge, or Quilt). Also, don’t forget to install the required Collective library in the mods folder. If the mod still doesn’t work, remove other mods one by one to find conflicts, and restart Minecraft after changes.
Why does Minecraft crash when I use the Full Brightness Toggle mod?
This usually happens if something is missing or mismatched. If you’re using Fabric, make sure to install Fabric API and Mod Menu. You also need the Collective mod installed. Check that your mod loader matches the mod version. For Minecraft 1.20.5 or newer, use Java 21.
Why doesn’t the G key toggle the brightness?
Sometimes another mod is already using the G key, or the keybind didn’t save correctly. Go to Settings > Controls > Key binds, search for Full Brightness Toggle, and change the key to something else like H or B. Then restart Minecraft to apply the change.
FAQs about Full Brightness Toggle mod
Can I use the Full Brightness Toggle mod on multiplayer servers?
Yes, but it depends on the server. Since the mod only changes your screen brightness, most servers won’t detect it. Still, some competitive servers might flag it with anti-cheat plugins. Always check the server’s rules before using it.
Why is my game still dark even after pressing the toggle key?
If your screen doesn’t get brighter, it might be because the mod wasn’t installed correctly, or you’re missing the Collective library. Also, make sure you installed the right version of the mod and loader. Check your keybind settings too—it might be in conflict with another mod.
Does the Full Brightness Toggle mod work with OptiFine?
Yes, but only if you’re using Forge. If you’re using Fabric, NeoForge, or Quilt, OptiFine might not work well. Try Sodium + Iris Shaders as an alternative for better performance with those mod loaders.
