That was an interesting feature to learn about, but I ended up importing the FP character and changing the possessed pawn to that when you enter the room and to the third person character when you leave it. I definitely have this tutorial earmarked for later, though! 
Hello,
I was wondering if anyone could direct me to a video, or kindly explain if it is possible to do the following:
I have a third person game I am working on, having started with the UE4 third person starter content. What I WANT TO DO is have a player go into a “Shooting” Gallery, where they are then using the First Person starter content player mesh, with the shooting gun, and arms. I want to be able to have the player back out of the room and go back to being 3rd person perspective once more.
It would be ideal if I could set the FP perspective to a key, like rolling the mouse wheel, and only having it available in the room [Box Collider].
Anyways, its just an idea. Thanks!
