Revealing secret rooms

Sorry, newb question here. I see the secret rooms on the DM layer in Tomb of horrors, not on the player layer. How do I reveal those rooms when they find them without revealing the rest of the rooms? And more importantly, how do I switch layers? I need step by step help please...

Going to take your questions in reverse order so that the directions make sense. To change what layer you are working on, simply select the layer you want from the menu on the left of the vtt: To move objects between layers, you just right click the token and select what layer you want to move it to from the layer drop-down: You can also enable  advanced keyboard shortcuts from your settings menu and do all of this with keystrokes: Hope that helps and happy rolling, Scott

Thank you for the quick reply! I did not notice the secret rooms being objects. I'll check this out and report back if I run into any other issues. 

Happy to help.
