neverminds I am just dumb
here was the problem or even if you don’t know how to stream custom traffic:
create a ressource where you put your custom popgroups.ymt and your fxmanifest.lua
and don’t forget to declare your file (like me duh):
files {
‘popgroups.ymt’,
}
data_file ‘DLC_POP_GROUPS’ ‘popgroups.ymt’
and if you have addon vehicles in your traffic make sure to start them BEFORE your custom popgroups or else they don’t spawn.
there ya go!
