The shader utilizes noise texture generation and tiling offset techniques to create a visually stunning effect that makes the skybox appear covered in a layer of dust.

The noise texture generation technique involves creating a random pattern that is applied to the skybox, creating the impression of dust and dirt particles that are scattered across the environment. The tiling offset technique is used to create the illusion of movement, making it appear as though the dust particles are slowly shifting in the breeze.

This effect adds to the overall atmosphere of the scene and makes it feel more immersive for the player.
