I use one wings file for all the models. Just because they're really simple and I don't want the clutter of all the wings project files. If I need to I can just remodel the object easily.
Edit: Also, with this mod I'm focusing primarily on the gameplay (in case you couldn't tell). The visuals aren't that much of a priority to me. As long as you can tell what's going on I don't really care what it looks like

. My largest focus right now is getting this armor.txt file to work.
So basically I'm not going to go out of my way to learn how to make UV maps stunning eye-candy. I will go out of my way to make sure everything is perfectly balanced and works.
Edit again: Okay so the armor file suddenly decided to work. PA 3 will be released soonish. I just want to fine tune some balance problems.
