The levels page will allow you to toggle the assets on different levels of the environment. This is useful for sorting assets that would be available on different levels of a building or structure.
To toggle a level, click on the green or red button to the right of the level you wish to toggle. If the button is green, it means that the level is currently on. If the button is red, it means that the level is currently off.
To select a level, click on the button with the name of the level you wish to select. Clicking on it will turn on the selected level and turn off all other levels.
Additionally, you can click on the All Levels button to toggle all levels at once.
