Room markers

Room markers are objects in The Sims 3 that look like shiny silver spheres. They dictate the behaviour of certain spaces on lots, and some have menus accessible via the Shift, Ctrl + click interaction.

Room markers can be added to a lot using the buydebug cheat.

Tomb fogger
The tomb fogger was introduced in The Sims 3: World Adventures. Placing this object in a room will turn that room into a tomb room that is not visible until a Sim enters. A sound effect plays when Sims first enter rooms with this marker. Using the Shift, Ctrl + click interaction on this object allows builders to set different genres of tomb, such as 'Tomb of Death'. Changing this setting changes the message players receive when they first enter the room.

Hidden room marker
This marker was introduced in The Sims 3: Late Night. Placing this object in a room on a residential lot will turn the lot into an apartment and hide the room that it is placed in. If there is a door into this room it will act like townies live there.

Public room marker
This marker was introduced in The Sims 3: Late Night. Placing this object in a room will turn a residential lot into an apartment and prevent players from editing the room in build or buy modes without using cheats. Also, any objects in the room will not count towards the lot value.

Skip level room marker
This marker was introduced in The Sims 3: Late Night. Placing this object in a room will turn the lot into an apartment and prevent the player from seeing the contents of this level.
