About this Mod

DimensionAccess is a lightweight server-side Fabric mod that gives server operators full control over which dimensions players can access.

Features

Disable any dimension - prevent players from entering specific dimensions such as the Nether or the End
True cancellation - the teleport is blocked before it happens: no achievement, no chunk loading, no side effects
Live reload - update the config without restarting the server
Auto-complete - commands suggest valid dimension identifiers automatically

Commands

All commands require OP level 2.

`/dimension disable "<id>"`	Block a dimension (e.g. `"minecraft:the_nether"`)
`/dimension enable "<id>"`	Re-allow a previously blocked dimension

Frequently Asked Questions

DimensionAccess server crashes on startup – what to do?

Most common cause: wrong fabric 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 (1.21.1). You can switch loaders with one click in the panel.

Is DimensionAccess compatible with fabric?

DimensionAccess officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with DimensionAccess – how to optimize performance?

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