Hey, Ekalb.
I finally figured out how to get all of the textures working with Zmodeler. I was able to reposition the Whelen Liberty where it needed to go on the Vapid and I was able to position the siren lights correctly. The car ran great in the game, however, the light bar doesn't render at a certain distance in-game. When I get close enough, it appears. In other words; The car's look like slicktops from a distance with flashing lights floating above them.
Any idea what it could be?
