You can’t make a good dungeon without having some secrets, right? Hidden traps, secret doors, concealed corridors, illusory floors, invisible enemies and fake treasure. Now, placing invisible enemies on the map is dead simple (trick being not actually placing them at all) but how can I make a map with a secret corridor that I can reveal and hide at will, and not betraying it’s existence when it is hidden?
CC3+ has nice tools for adding corridors to your map, but you have do decide if they should break the wall or not when connecting to an existing room or corridor. And this is where the challenge begins. It is easy enough to temporarily hide something by putting it on it’s own layer so toggling the visibility of the corridor is easy, but if you chose to have it break the wall when placed, you would still have that hole there when the corridor is hidden. Now, that isn’t actually a good way to keep it secret. On the other hand, if you chose to not break the walls, then there will be walls blocking the corridor even when it is revealed, which look a bit weird, and we can’t have any of that, can we?
