First of all thanks to Zenophon, I learned a lot of things thanks to him.
I tried to change the vehicle classes in "Zen_SpawnAmbientVehicles.sqf" for spawn vehicle from addon :
using the config file "Zen_ConfigGetVehicleClasses.sqf" but it doesn’t work. Maybe it’s not the right way to do it?:
I tried a lot of different ways but I don’t understand how to choose the vehicle I want to spawn. Is it possible to do it directly with the classname?
Thanks!
