Hi. Well the vehicles.meta file was the problem. I changed the vehicles but now i have a different problem. Some new vehicle models i've replaced fbi cars with have no color in their sirens. When i'm away from them the color becomes the nice blue-red. When i get close at them or when i drive the vehicle there is no color at all. Maybe a white color. The way i open the sirens on these vehicles is by pressing j,k,l buttons and then changing the sound of the siren with 1,2,3. The vehicles in which sirens work with no problems, have their sirens open by pressing E and J toggles the sound on - off. Maybe the xml files from previous fbi vehicles? maybe something else?
