Thanks very much,
I hear the Rich Diesel tutorial is good, so I will probably use that. I started off using the one off the PCGamer Dvd, because I couldn't get online, but Now I will use the others, thanks.
Dispite my amazing ability to figure things out I never really thought of using the spawn point for the map sizes, thanks.
At the moment I am just messing around linking rooms with corridors. I haven't figured out how doors work yet, I can only make ones on SP to force push open.
My first test level ended up with a light in the middle and alot of black patches around the room, but I'm sure I will become familiar with the lighting techniques.
I hope to make some interesting maps.
