optterrain Console Command

The `optterrain` command in Valheim is used to optimize the terrain in the specified area of the map. It is specifically designed to convert older terrain modifications to the new system. This means if there have been updates to the game that change the way the terrain is generated or rendered, this command will apply those updates to the area around you. This command might be especially useful after large updates, where significant changes have been made to the game's terrain system. Applying these changes can prevent potential bugs or glitches that could occur if the old and new systems were to interact. It's particularly handy if you've been building large bases or other structures, as it ensures that the terrain will render correctly with the updated system.
