Was able to fix the charger, but it uses the police2 vehicle sound, bike might end up having to use that sound as well. The vehicles.meta had every single car in the game inside of it so I’m testing to see if taking out all the vehicles except the bike and then changing the bike sounds to activate the sirens and engine sounds will work. Will let you know in a few!
UPDATE: Both the bike and Charger are working with sounds and sirens! If you would allow me to Bdkohn, I can upload them somewhere and you can take them and replace the files you have! If not that’s fine I don’t need any credits or anything, just here to help the community!
