vehicle textures not being displayed properly

i installed 2 vehicle packs yesterday. 1 was an addon (came in its own dlc) and 1 was regular. i installed that one as addons in albo's dlc. the other one i changed all the names in the dlc it came in. (for jurisdictions+). all vehicles have carvar and meta entries. in openiv they look fine but in game they all have serious texture issues. either no texture or shifting flickering textures. like the bump map for the tire will be the vehicle skin. the cars do spawn and drive etc without crashing the game. i have at least 1 other addon dlc that the cars are spawning properly.
