I have 15 scenes in my file. When I add a new tag Everything in it becomes visible in all scenes. However I only want it visible in 1 of 15 scenes. Is it possible to make in invisible in the other 14 scenes without doing it manually? (Like a button - make in only visible in this scene?)
Use Auto-Invisible Layer from the Extension Warehouse. When it is enabled, new tags will not be visible in existing scenes. After that you can turn on the tag for those scenes where you want it to show and update the scene.
