Farm Type Manager is a popular tool for creating custom content for your games. It allows you to spawn large objects (a.k.a. large blocks) and even edit their properties (e.g. texture, color, and other data fields) to create unique maps and worlds.

A content creator can configure the number of large objects to spawn per day, which areas or terrain types they can spawn on, the chances of spawning each object type, and more. The config.json file is saved to your game's data folder and will be loaded each time the game starts.

The tool also supports content packs, which can configure other mods to spawn automatically. If any of your other mods come with "[FTM]" folders, they will be used by Farm Type Manager to spawn custom content.

The whereami command can be used to display information about your current location.

The spawn.js and spawn.json files are saved to the corresponding folders and will be loaded each time the game starts.
