I tried to swap the Pc model Ghost onto the Warthog (in Hex Workshop) and I got an exception. I was just wondering if anyone knew if it was possible, as HMP doesn't seem to have a tag for it. I probably just screwed up.
EDIT: Oops wrong forum.

you cant just go and switch the models.. if your looking at the values, the ones labled models are a lot more then that.. youll have to switch the binary models to get it to work perfectly.. otherwise it tries to also spawn the wrong physics.. and several other things dont work correctly
