Skyloom

Press one key, pick a sky, keep playing. No resource pack shuffling, no restart, no config files.

What it does

Minecraft's sky is the same blue box in every world you ever load. Skyloom puts a menu in front of it. Open it with I, pick a sky from a list, and the world above your head changes on the spot. Change your mind ten seconds later and pick another one. Nothing reloads, nothing stutters.

Getting skies

Browse them in game. The Browse tab lists skies you can download with one click. They land in your My skies tab as soon as the download finishes, and they stay there. No browser, no unzipping, no dragging files into folders.

Or bring your own. Skyloom reads OptiFine and MCPatcher custom sky packs, the format that thousands of skies have already been made in over the last decade. Drop the zip into .minecraft/skyloom/skies and hit Rescan. It reads .properties files, fade times, blend modes, weather conditions and rotation exactly the way OptiFine does, so packs made for OptiFine work without being converted.

The menu

• My skies — everything installed, with a preview of each one. Click to wear it, click Turn off to go back to vanilla.
• Browse — the download list, with a progress bar and a badge on anything already installed.
• Settings — switches for the sun, the moon, the stars, the sunrise glow, the clouds and the weather. Turn off whatever gets in the way of the sky you picked. There is also a brightness slider, a rotation toggle with a speed control, and an option to keep custom skies in the Overworld only. Every control takes effect the moment you touch it.

My skies and Browse both have a search box and category filters, so a hundred installed skies stay findable.

Compatibility

• Sodium — tested, works.
• Iris — tested without a shaderpack, works. With a shaderpack enabled the shaderpack draws the sky itself, so what you see is up to the shaderpack rather than up to Skyloom. That is how shaderpacks work with every sky mod, not something Skyloom can override.
• OptiFine — not applicable, OptiFine does not run on Fabric. Skyloom reads OptiFine's sky format, which is the part you actually want.
• Requires Fabric API.

About the downloads

The Browse tab fetches a list of skies from a file the mod author hosts, and downloads a sky only when you click it. Nothing is downloaded in the background and nothing is downloaded on startup. Downloads are HTTPS only and are checked to be real zip archives before they are kept.

You can point the mod at a different list by editing catalogUrl in config/skyloom.json, so a server community or a modpack can host its own collection.
