About this Mod

A Glowstone Prism cluster from below

Glow removes the Nether's glowstone blobs in favour of groups of large glowstone crystals which light up the Nether ceiling pleasantly, and provide a new danger with falling stalks of glowstone which explode when they hit the ground.

The glowstone prisms fall randomly at a slow pace, and the player can also use any projectile to destroy a prism and cause the blocks underneath it to fall.

A prism cluster at a faster random tick speed.

Frequently Asked Questions

Glow server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Glow compatible with forge and neoforge?

Glow officially supports forge, neoforge for Minecraft 1.21.1, 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Glow – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Glow 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.
