About This File
To Install textures, use OpenIV to install the vehicles as directed,
open the .ytd (and sometimes also the +hi.ytd file), and replace the texture.
Use any CVPI you like.
If the model has multiple textures (i.e. car_sign_1,car_sign_2, etc.) you can delete the all but car_sign_1 to ensure only these textures spawn.
