The sky's the beginning.

Cirrus is a client-side skybox overhaul that stays close to Minecraft's vanilla style. It adds layered clouds, richer nights, and weather-aware effects, all with an in-game config.

Client-side only. You can use Cirrus on multiplayer servers without installing it on the server.

Cirrus is designed to be used without Iris or shader packs.
