sorry my man as the other guy said you're not gonna get any answers here. but u definitely will in the ingame forums on zone. that quite frankly is actually like the only thing keeping the game alive so definitely check that out.
funny enough though i can answer, there's really no such as "weapon templates." well there are, but they're really not needed. no one uses them because all you have to do is draw whatever you want, give it 4 views and boom. templates exist for things like heads and bodies because there's size limits and all that. weapons don't. you can make whatever you want
