This mod randomly generates Islands throughout the world. Not your simple prebuild survival island.

Features:

Starter hut
Loot Barrels spawning in the ocean (making it seem like loot from wrecked ships)

Frequently Asked Questions

IslandGen server crashes on startup – what to do?

Most common cause: wrong neoforge 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 IslandGen compatible with neoforge?

IslandGen officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with IslandGen – how to optimize performance?

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