Sky

Inherits from: Instance → Object

The Sky object, when placed inside Lighting, changes the default appearance of the experience's sky. This object's skybox is composed of six sides, like a cube. Rotation of the skybox can be changed through SkyboxOrientation.

The skybox sun, moon, and other celestial objects remain visible unless you turn off the CelestialBodiesShown property. By adjusting the StarCount property, you can change how many stars appear in the sky at night.

This object can also be used as a cubemap for reflections in ViewportFrames, in which case only the Sky object's six‑side Skybox[…] properties are used. For details, see viewport frames.

Sky.SkyboxOrientation

Changes the orientation of the skybox surfaces. This property takes a Vector3 of degree values in the typical XYZ order, but applies rotation first around the Y axis. After applying the Y axis rotation, the orientation is applied to the X and Z axes to allow for predictable control over complex movements. Your camera and object orientation can affect how this rotation appears to be applied.

An easy way to script an orientation animation is to spin around the Y axis (keeping the horizon level), then tilt this axis by setting X and Z to a fixed value:

local Lighting = game:GetService("Lighting")
local RunService = game:GetService("RunService")

local sky = Lighting:FindFirstChild("Sky")

local ROTATION_SPEED = 5  -- In degrees per second

RunService.Heartbeat:Connect(function(deltaTime)
	sky.SkyboxOrientation = Vector3.new(
		30,
		(sky.SkyboxOrientation.Y + ROTATION_SPEED * deltaTime) % 360,
		0
	)
end)

See here for further info and limitations.
