Thanks for the extra info.
If you type in “hidden” in the details
pane search bar the options should
appear, though you can also find them
in the Rendering section of the
Details Pane when the actor is
selected
Useful but scene or map wise there is no indication if something is visible or invisible. Rendering/Visible has no link to the World Outliner.
This would give you greater control
over what is seen/not seen when you
need it during editing and can help to
keep track of various assets placed
within larger levels.
This is useful but again ignored during saving/loading and during Play.
