If you need to hide an object within a scene without deleting it, follow these steps:
On the storyboard, go to the scene where you want to hide a layer.
Select the layers icon on the scene viewport to open the layers tab on the left panel.
Find the visual or object you wish to hide and click the ‘eye’ button next to it to hide it.
The hidden object will be promptly concealed within the scene viewport.
To reveal the previously hidden object, simply click the ‘eye’ button again. It will become visible once more within the viewport.
Note that the background is a fixed layer that can't be hidden or deleted.
By following these steps, you can easily hide and unhide objects within your scenes as needed, without the need for permanent deletion.
