CaveBiomeAPI Mod [1.17.1, 1.16.5] for Minecraft is a core library mod programmed by blackgear27, programmed for the purpose of booting and providing resources for other mods, so it often appears in the “required” section when installing.


Core mods are currently a trend with maximum resource savings and can support many mods at the same time. Thanks to the existence of these Core Mod types, updating, changing and fixing bugs for multiple mods at the same time becomes simpler. Almost all Mod Developers who have programmed many mods use this programming method.

Programmed as a support mod, CaveBiomeAPI will not provide any effect when installed independently into Minecraft, sometimes these mods only provide a few small items. Instead of adding new content to the game, it will provide documentation, code and pre-built frameworks so that other mods can work properly. The mods that CaveBiomeAPI supports will often use a common code in the structure, so to reduce file size and save time and optimize, blackgear27 has combined this code into BGCore. Please note that if you do not install this mod before installing the mods that need it to work, the system will report a game error, causing a crash and not being able to load into the main menu.
