How to Tell If You Need Cumulus in Your Mod List

If you found Cumulus in your modpack or mods folder and noticed it adds nothing to your creative inventory, that is completely normal. Cumulus is a background utility mod rather than a content expansion.

What Cumulus Does in Your Game

Cumulus adds zero blocks, items, tools, or creatures to your survival worlds. Its sole job is providing background tools that let other mods build custom title screens, moving panoramas, and special main menu buttons. If you install Cumulus completely by itself, your gameplay and worlds will look and behave just like vanilla Minecraft.

Checking Before You Remove It

You only need Cumulus installed when another mod in your list specifically asks for it—most commonly mods from the Aether series.

1. Check your mods folder to see if you are running the Aether series or other mods known to add custom title screens.

2. If you remove Cumulus while a dependent mod is still installed, Minecraft's mod loader will halt startup and display a missing dependency screen naming the mod that requires Cumulus.

3. If you have already removed the content mods that asked for Cumulus, you can safely delete Cumulus from your mods folder without corrupting existing worlds, breaking chests, or losing any items, since nothing inside a world save comes from this mod.
