Settings to apply

Values to set in each file, one per line, grouped by the file they belong in. This is not the file's own format: copy the values across rather than pasting the block. Dotted names are nested, so visibility.public means a public key inside a visibility object.

[servertest.ini]
MaxPlayers=6
PauseEmpty=true
PVP=false
SaveWorldEveryMinutes=30
HoursForLootRespawn=0
MaxItemsForLootRespawn=4
AntiCheatProtectionType1=true

Notes

Verified against Build 42 before it reached Stable. Build 42 went Stable on 29 July 2026 and hotfixes ran to 42.20.4 on 26 August, which removed the Lua loadstring and loadstream methods and broke any mod that used them. Re-test this recipe on 42.20.4 before relying on it, and check the modpack through the Workshop Importer, which flags items untouched since that date.
HoursForLootRespawn=0 disables loot respawn. Increase if you want regenerating loot.
Pair with low zombie population in sandbox settings for a relaxed experience.
Auto-save every 30 minutes balances data safety with disk wear.
