Skyloom
by yxusuf05
Skyloom lets players swap the sky in-game from a menu, using skies in the OptiFine and MCPatcher custom sky format.
What it does
A menu opened from the world lists every sky installed in the skyloom folder, and a preview shows each one before it is applied. Picking a sky takes effect immediately, so a player can change mind a few seconds later without a restart or a resource pack reload. Switches turn the sun, moon, sunrise glow and clouds on or off, and a click can put the default Minecraft sky back.
A browse tab fetches skies that can be added to the game, shows a progress bar while each one arrives, and marks entries that are already installed. Packs are unpacked by the browser, so a zip does not have to be extracted by hand. Players can also drop their own zip into the skies folder and press rescan to load it.
Skyloom reads the custom sky packs made for OptiFine over the last decade, including their property files, which set timing, blending, weather conditions and rotation. It runs on the Fabric loader and needs Fabric API. The mod is client-side only, so only the player needs it, and the code is under the MIT License, though the project is not open source. Files exist for 1.21.9, 1.21.10 and 1.21.11, with 1.0.0 for 1.21.11 as the latest build.

Use cases
Who it’s for: Players who want to change the sky without editing resource packs or restarting the game. It suits single-player worlds and clients that join servers, since only the client needs the mod.
How it compares
Dark Sky is also a Fabric client mod with MIT licensing and is open source, for 1.19.3 – 1.21.11. Skyboxify is an open source client mod under the GNU General Public License v3.0 only, for 1.21 – 26.3. Skyloom is not open source and covers 1.21.9 – 1.21.11, so the two differ in version range and license.
