About this Mod

UnderWater Pressure is a server-side mod that adds semi-realistic water pressure. The deeper a player goes underwater, the stronger the pressure becomes. Staying under high pressure for too long results in instant death. Time until death, enabling/disabling the mechanic, and debug mode are configurable via Config. Armor protection against pressure is also available: you can configure single items (e.g., turtle helmet) or full armor sets. Creative and spectator mode players are immune to pressure.

Frequently Asked Questions

UnderWater Pressure 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 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is UnderWater Pressure compatible with forge?

UnderWater Pressure officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with UnderWater Pressure – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if UnderWater Pressure 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.
