Hey, thanks for the replies.
Basically, I just need to change a spawn area from having 3 doors to a long open space, but with a barrier that stops shots and projectiles going through but still allows players through. I'd also need a few ramps and some glass put in.
I am sure Trade maps are lame to work on. xD
Feel free to add me so we can talk a little more in depth if you'd like. I feel bad for asking but I've not a clue how to use Hammer. I even tried! Y^Y
