Oh god is this going to suck.

I've found a program that will convert Source engine maps (built in the Hammer editor) to Source engine models. It's going to be easier than learning/doing it in maya/xsi/blender ect, and it might provide a starting point, but it is going to be as ugly and as blocky as, well, the original game.

But it's still going to be better than 2K's version.
