Terraria server settings explained
Updated 2 November 2026 · 11 settings · Terraria · By Exclsv Support
Every setting in the Terraria settings form in Exclsv HQ: what it does, where it lives, its default and the values it takes. File settings are in serverconfig.txt; to edit it by hand, stop the server first, because a game can rewrite its settings while it runs.
On Exclsv you don’t need to edit the file by hand: change a setting in HQ’s form and HQ writes it for you, with the server stopped.
Settings marked “Set in HQ” are changed in HQ’s form only: HQ applies them every time the server starts, so an edit elsewhere doesn’t last.
