@Krysti, are you playing TS3 or TS4? I only ask because you said you got the lot from the gallery which is TS4 while TS3 has the exchange plus the cheat codes is different for the game.
First, TestingCheatsEnabled True
Then, BuyDebug On
This will allow you to see room markers, fog emitters, and spawners. BuyDebug assets are on their own Buy tab, in Sort By Category, at the top of the selection window.
Hidden Room Markers look like a metallic sphere, rather large - I think the footprint is 4x4.
