Fake Locked Door

In this tutorial you will learn how to create fake locked doors.
I mean doors that you were never supposed to open but you can hear a sound of locked latch or something.
And this is the easiest and cleanest way to do it.

Steps:

1. Create a door and multisource

-Create a func_door
-Create a multisource

2. Change propterties.

-In multisource properties change both it's name and target to same value e.g. "ms_fake"
-In door properties change Master value to multisource's name e.g. "ms_fake"

3. Change door locked sound so you can see effects.

Change func_door's locked sound and make sure that your fake door is not making a leak,
because you need to remember that func_door's are not sealing your map from void like normal brushes.
