Like the title suggests, is it possible to change the siren category for a specific vehicle? Say I want to use the FIB siren on the unmarked cruiser instead of the generic police siren, is there a way to do this and if so... how?

Each model entry in vehicles.meta has a "audioNameHash" line. If you want to change police4 to use fbi's siren, make the line look like this:

<audioNameHash>fbi</audioNameHash>

 This will change all of the vehicles sounds, however, not just the siren. No method to do otherwise is know at the moment.

This method works fine for me, drag the file from Open IV to your desktop, then edit it with notepad ++, once your done add it back into Open IV and your good to go
