How to Change Your Space Engineers Server Name and World Settings

Space Engineers splits its settings in two. The dedicated config holds the server identity, and the world's own config holds the rules of the game inside it.

The two files

Stop the server first. Space Engineers rewrites both files on shutdown, so edits made while it runs are lost.

In the panel open Files:

• instance/SpaceEngineers-Dedicated.cfg, the server settings.
• instance/Saves/<WorldName>/Sandbox_config.sbc, the world settings.

Both are XML, so a missing closing tag stops the server loading and the console says so.

Server name, password and world selection

In SpaceEngineers-Dedicated.cfg:

<ServerName>My PlayNHost Server</ServerName>
<ServerDescription>Survival, no wolves.</ServerDescription>
<ServerPassword></ServerPassword>
<WorldName>My World</WorldName>
<LoadWorld>/home/container/instance/Saves/My World</LoadWorld>
<AutoSaveInMinutes>5</AutoSaveInMinutes>
<PauseGameWhenEmpty>true</PauseGameWhenEmpty>
<IgnoreLastSession>false</IgnoreLastSession>

• LoadWorld is the full path to the save folder. This is how you switch worlds.
• IgnoreLastSession set to true forces the server to load the world named in LoadWorld rather than resuming whatever it had open.
• Do not change ServerPort or SteamPort. They must match the ports allocated to your server.

World rules

In Sandbox_config.sbc, inside <SessionSettings>:

<GameMode>Survival</GameMode>
<InventorySizeMultiplier>3</InventorySizeMultiplier>
<AssemblerSpeedMultiplier>3</AssemblerSpeedMultiplier>
<AssemblerEfficiencyMultiplier>3</AssemblerEfficiencyMultiplier>
<RefinerySpeedMultiplier>3</RefinerySpeedMultiplier>
<WelderSpeedMultiplier>2</WelderSpeedMultiplier>
<GrinderSpeedMultiplier>2</GrinderSpeedMultiplier>
<MaxFloatingObjects>56</MaxFloatingObjects>
<EnableIngameScripts>true</EnableIngameScripts>
<EnableSpectator>false</EnableSpectator>
<AutoHealing>true</AutoHealing>
<EnableDrones>true</EnableDrones>
<EnableWolfs>false</EnableWolfs>
<EnableSpiders>false</EnableSpiders>

MaxFloatingObjects is worth attention. Floating debris is one of the main causes of a Space Engineers server slowing down, and lowering it helps directly.

Slots

Your plan's slot count is applied through the MAX_PLAYERS variable on your server's Startup Settings page, reachable from the server overview. <MaxPlayers> in the world config does not add slots. Upgrade the plan in the billing area to run more.

Apply and verify

Save, start the server, and watch the console. If the world does not appear to have your changes, check that you edited the save under instance/Saves/ that LoadWorld actually points at. Servers with several worlds on disk are usually edited in the wrong one.
