Alright, so for my first map ever, I'm trying to make it by making vertices and connecting them with polys. I don't have all that much of an idea of what I'm doing, so does anybody know of any tutorials about making maps with vertices and polys? (A simple tutorial would be nice).

i gave you a link to higuys terrain tutorial to practice...
thought you were using it?

Well, I am, but for a newbie, it's a little bit complicated, but has definately helped me out though.
