Unsolved Traffic vehicle group for specific map

Hello, how do I set a vehicle group as traffic default for a specific map?

Some vanilla maps (like WCUSA) have a vehicle group within the levels/levelname folder. I did that aswell but how to tell the game to only use this vehicle group for the traffic?

Thanks!

Has anyone figured this out?
The same problem applies to the speedlimits the traffic bots drive.

I created a zone with the corresponding tags:

Spoiler: city.sites.json

"zones":[
{
"bot":{
"active":false,
"normal":[
0,
0,
-1
],
"pos":[
56965.576171875,
7485.5014648438,
78.832710266113
]
},
"color":[
1,
1,
1
],
"customFields":{
"names":[
"traffictype"
],
"tags":[
"africa"
],
"types":{
"traffictype":"string"
},
"values":{
"traffictype":"africa"
}
},
"name":"trafficzone",
"oldId":3414,
"top":{
"active":false,
"normal":[
0,
0,
1
],
"pos":[
56965.576171875,
7485.5014648438,
91.84489440918
]
},
"vertices":[
[
57181.228515625,
8058.0961914063,
84.073699951172
],
[
56481.21875,
8371.2998046875,
84.396957397461
],
[
56496.9375,
6790.2983398438,
83.832710266113
],
[
57449.93359375,
6599.703125,
86.84489440918
]
]

I created this vehicle group and put it in the root folder of the map:

Spoiler: africa.vehGroup.json

{
"data":[
{
"config":"afr_traffic_miramar_ute",
"model":"miramar",
"paintName":"Alpine White",
"paintName2":"Cream White",
"paintName3":"Champagne"
},
{
"config":"afr_traffic_pessima_1",
"model":"pessima",
"paintName":"Bermuda Blue",
"paintName2":"White",
"paintName3":"Steel Gray"
},
{
"config":"DX_M",
"model":"midsize",
"paintName":"White",
"paintName2":"Pearl White"
},
{
"config":"afr_traffic_ETK_800",
"model":"etk800"
},
{
"config":"afr_traffic_covet",
"model":"covet",
"paintName":"White"
},
{
"config":"afr_traffic_ETK_I",
"model":"etki"
},
{
"config":"d15_fleet_M_facelift",
"model":"pickup",
"paintName":"White"
},
{
"config":"h15_vanster",
"model":"van",
"paintName":"White"
},
{
"config":"4wd_facelift",
"model":"roamer"
},
{
"config":"d15_farmhand_M",
"model":"pickup",
"paintName":"White"
}
],
"name":"africa",
"tags":["africa", "traffic", "generic"],
"type":"custom"
}

The traffic in WCUSA is setup identical. I can´t figure out why it works in WCUSA but does not in my map. The same logic applies to the speedlimits within a zone. It does not work either.

Has anyone set this up correctly before and has an idea why it does not work in this case?

 

Got no idea sadly.
