So this is my first official post (Yay). I have just gotten into mapping on radient and i want to have more potential in my maps. I have been looking all over the web for custom bo1/2 weapons but i cant find them, i have also been wanting to add special additions to guns, for example, is there anyway to make it that when you fire a bullet gun, the zombie hit goes on fire? And lastly, i was wondering how i add my own custom machine guns as a reskinning of waw ones and add my own camo to it as well, i know this is a lot to ask and I'm really sorry but it has been just so frustrating trying to find this stuff.

thanks in advance.
