Sky Domes

• sky is always visible, day_sky fades in during the day and night_sky at night.
• Works in the Nether and the End, including during the Ender Dragon fight.
• Textures are mapped as a 360° panorama (2:1 images look best): the top of the image is the zenith and the middle is the horizon.
• The left and right edges of the image blend smoothly where they meet. Use rotation to move that spot, for example behind mountains.

Multiplayer

To apply CustomSkyboxes effects to other players, use:
Client Execution Mod

Or use the CustomSkyboxesPlugin (Paper/Spigot 1.20.1+) to control the skies of @a or any player from the server:

/customskyboxesplugin set <@a|player> <type> <texture|color> [args...]
/customskyboxesplugin clear <@a|player> <type|all>
/customskyboxesplugin biome set <@a|player> <biome> <type> <texture|color> [args...]
/customskyboxesplugin reload <@a|player>

Players need the mod installed and the textures in their resource pack.
