Atmospherics by Beash lets you overhaul Minecraft’s visuals with real‑time control of fog, sky, clouds, stars, haze, and day/night on a per‑biome basis, featuring transitions and live previews. The in‑game menu (hotkey B by default) includes a preset library, live info panel, cloud and comet/star customization, solid cloud rendering, and import/export for presets so creators can craft and share biome visual themes.
The mod is available for Fabric 1.21.11–26.1.2 so far.
If you’re looking for a modpack that includes Atmospherics and additional immersive mods, try our new BM: Mirabilis modpack, a Vanilla++ experience that combines mods like Atmospherics’ with the popular tweaks of Beyond Mines.
