Collective Library FAQ

10 questions players actually ask, answered.

Do I need to install Collective Library separately?
Yes. Collective Library is a required dependency for any mod that lists it as a requirement. Download and install it to your mods folder before installing the dependent mod, or the game will crash on startup.
What happens if I remove Collective Library after installing mods that need it?
Your game will crash when loading any mod that depends on Collective Library. Always keep it installed alongside the mods that require it.
Can I use Collective Library with mods from other modders?
Collective Library is a shared library only for Serilum's mods. Other modders' mods won't use it, but there's no conflict—you can run Collective Library alongside any other mods.
Does Collective Library do anything by itself?
No. Collective Library has no in-game features or content on its own—it only provides code that other mods use behind the scenes.
Why do I need Collective Library if I'm only using one mod?
If that mod lists Collective Library as a dependency, you need it installed for that mod to function, even if you're not using multiple dependent mods.
Will using multiple mods that need Collective Library cause lag?
No—Collective Library actually optimizes performance by combining shared code and events from multiple mods into a single process, reducing overhead compared to each mod running independently.
How do I know which version of Collective Library I need?
Check the mod's download page or in-game mod list; it will specify which Collective Library version is required. Use the version that matches your Minecraft version and the dependent mod's requirements.
Can I use an older version of Collective Library with a newer mod?
Not reliably. Always use the Collective Library version specified by the mod you're installing—mismatched versions can cause crashes or unexpected behavior.
What should I do if a mod says it requires Collective Library but won't load?
Verify Collective Library is in your mods folder, check that both versions match your Minecraft version, and ensure Collective Library loads before the dependent mod (it usually does automatically).
Is Collective Library safe to use?
Yes. Collective Library is an official shared library maintained by the same developer as the mods that use it, and it contains only code optimization—no malware or unwanted features.
