Enable or disable teleportation to the Nether

Access dimension settings

Run /function clean_rtp:__config as an operator to open the settings menu. Look for the dimension list or approval settings.

Toggle Nether access

The data pack includes all standard vanilla dimensions on the approved teleport list by default, including the Nether. Use the config menu to enable or disable Nether teleportation for your server.

Understand height restrictions

If you keep Nether teleportation enabled, the data pack automatically caps teleport height at Y level 126 by default. This prevents players from spawning on the bedrock roof and getting stuck. Server operators can toggle between Y 126 and Y 254 limits depending on custom world setups.

Verify dimension changes

After adjusting settings, use /trigger rtp and observe which dimensions players can reach. If Nether is disabled, teleports will only occur in the Overworld and End (if enabled).
