Hey,
I just started to create my first map. Ok, OK it is just a generic killbox but you got to start some where
Anyways I thought on adding rooms on the outside but I wanted to hide the entryway to the hallway leading to the other room. I have seen other maps that use the texture to hid the entry way and after the player passes through the entry, the player can turn around and see through the texture and shoot through the texture.
How do you do that?
