the 3 barrel thing is cause i used a modified nuke cannon skin, and had to put the skin on 3 times on that one surface across 3 polies, so the shadows that were in the skin make it look like 3 barrels.
yeah, me and a friend are making a mod, its probably gonna be for our own use, but just in case we make it public i'm not distributing any models. we'll see how it goes.
