This thread is for basic info on mapping for TTT, and to ask mapping questions in.
Setting up
To run your own game of TTT to test maps with, you'll need to have it installed as a gamemode. To do this, download the .zip and extract it into \garrysmod\garrysmod\gamemodes\, so you end up with a \gamemodes\terrortown\ directory. Make sure you don't put it in the \addons\ or \lua\ directories even though they sound like good places.
Might I inquire as to where this download is? I have maps just waiting to be converted into TTT but I cant until I have this DL.
Much appreciated.
