[Level Editor] Lock actors so that clicking does not select them

And what? Whoever asked a question expected a simple answer and not this ‘show’ of things that have nothing to do with the initial question. You talk about ‘layers’, but where is there any option in ‘layers’ to prevent something from moving or being selectable on the map / scene? It doesn’t exist, you just ignored the question to speak or write any nonsense here … at least try to help!
