Caelus API — FAQ

Troubleshooting & FAQ

My game crashes or a mod fails to load mentioning Caelus. Make sure the correct Caelus API build is present and matches the version the dependent mod requires.

I installed Caelus API but I still cannot fly. That is expected - it adds no flight on its own. You need a flight source: a normal elytra, or an item/slot from a mod that uses Caelus API.

Can I wear a chestplate and still glide? Only if a mod that depends on Caelus API adds a separate slot for the elytra/glider; Caelus API provides the attribute that makes such a setup possible.

Can I remove it? Only if you also remove every mod that depends on it; otherwise those mods break or lose their flight ability.

Is it a cheat / creative-flight mod? No. It governs normal elytra-style gliding only; it does not add free creative flight.

There are several files with similar names - which do I pick? Pick the build whose version matches your game version and the requirement listed by the mod you are installing it for.
