Cirrus

The sky's the beginning.

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

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.

What It Adds

• Three independently moving cloud layers with adjustable height, speed, opacity, and render distance
• Customizable morning, day, evening, and night gradients with smooth palette transitions
• Clouds that darken with storms and light up around lightning
• Narrow, layered lightning bolts with deterministic branching and electric glow
• Configurable stars with twinkle, color variation, and a North Star
• Occasional shooting stars with customizable trails, speed, color, and glow
• A rotating Milky Way and a subtle night-sky color palette
• Animated northern lights that appear in cold biomes by default (configurable!)
• A configurable End sky with moving clouds, lightning, and waves of spreading darkness

Every major effect can be adjusted or turned off!!!
