How to Disable the PCU Limit on Your Space Engineers Server

Published June 9, 2026 · By Host Havoc Technical Support Team

The PCU (Performance Cost Unit) limit controls how many blocks players can place on your server. This guide shows you how to disable it entirely.

This change is made in the save's Sandbox_config.sbc file. See Edit Save Settings for more background on editing save-level config files.

Before you start: Stop your server before editing config files.

Steps

  1. Log in to the Game Control Panel and navigate to your server.
  2. Stop your server.
  3. Click File Manager.
  4. Navigate to ServerSaveData\Saves\<YourWorldName>.
  5. Right-click Sandbox_config.sbc and click Edit.
  6. Find the following line:
    <BlockLimitsEnabled>GLOBALLY</BlockLimitsEnabled>
  7. Replace GLOBALLY with NONE so it reads:
    <BlockLimitsEnabled>NONE</BlockLimitsEnabled>
  8. Click Save & Exit.
  9. Return to the main control panel and start your server.

The PCU block limit is now disabled on your Space Engineers server.
