About this Mod

- Description -
Glow Up! is a simple datapack that adds a few minor (and unasked for) features to the glowier side of Minecraft. I felt Minecraft needed some way to use the glowing effect apart from the spectral arrow. That's why I made this pack. (You can probably make some cool minigames)
- Features -
- Glowing Leather Armor
- A new set of armor that makes the player glow when worn
- Only one piece of the set is needed to work, and every piece can be redyed
- Curse of Radiance
- A new curse that forces the glowing effect on the wearer
- Glowier Glow Berries
- Players are granted 15 seconds of glowing after eating glow berries
- Useful for those confusing multiplayer caving missions
- Glow Berrier Spectral Arrows
- Glow berries can be used as a substitute for glowstone dust in the spectral arrow recipe
With cheats enabled, you can use the command /function mglow:.item_selection to gain the custom items without needing to craft them.
- Installation -
Datapack: Just move the file into the datapacks folder of your world and start up the game. It's as simple as that!
Mod: Simply move the file into your mods folder of your world. The mod supports Fabric, Forge, and Quilt.
To uninstall, just remove the pack from the world/mod from your mods folder. Any special items will be left over, but it shouldn't affect performance at all.
- Compatibility -
This datapack is only compatible with 1.21 and will not work in any earlier versions

Glow Up! server crashes on startup – what to do?
Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21). You can switch loaders with one click in the panel.
Is Glow Up! compatible with datapack and fabric and forge and quilt?
Glow Up! officially supports datapack, fabric, forge, quilt for Minecraft 1.21. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Glow Up! – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Glow Up! consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
