# Skybox

Skyboxes are the environment that makes up a simulation. Skyboxes can be modified to include weather or affect the lighting of a simulation.

The skybox is a general simulation setting. Choose it from the **Skybox** dropdown in the scene menu, which also has Show Axis, [Set Spawn Position](https://docs.siminsights.com/hyperskill-studio-authoring/authoring-a-simulation/scene-layout/set-spawn-position), Undo and Delete.

The dropdown includes Nothing, Default, Day\_Blue Sky, Day\_Casual, Day\_Cloudy and Day\_Sunless. Scroll the list to see the rest.
