Spawn online cars naturally in traffic.

Description:
This mod allows online cars to spawn naturally in traffic accordingly to their nature (off-road cars spawn in the desert, expensive cars spawn in downtown, etc....).


Bugs and features:
After a cold start of the game, it can take a couple of seconds to see appearing the new cars, just drive around the block and they will show up in no time.
Also, if the player stays long enough in an area, the game will start to spawn a lot of the same vehicles again and again, my file doesn't edit anything else other than which cars spawn in which area. Rockstar stores those kind of parameters in files called "vehicles.meta" and "vehiclemodelsets.meta".
To kind of get around this little problem, I recommend editing the file "settings.xml" found in "Documents > Rockstar Games > GTA V" and change the value of "VehicleVarietyMultiplier" from 1.0 to 1.2, 1.3, 1.4 or 1.5, note that changing this value will slightly increase the video memory usage of the game.


Installation:
You need OpenIV for this, copy ""popgroups.ymt"" found in the archive to your ""Grand Theft Auto V > mods > update > update.rpf > x64 > levels > gta5"" directory, and replace the original file (it goes without saying that you should keep an original unedited file before replacing it).


Note 1:
Some online cars will spawn with the same color (mostly black), this is due to Rockstar configuring those cars in only one color as they are not supposed to be spawned around the city (you can only buy them). For me, I fixed this issue by editing some extra files buried into some folders and such. It can be tricky to upload the said files and guide users throughout a lengthy installation. But if it is requested, we'll make it happen through an OIV installation or something.

Note 2:
The archive contains a file in which there is a list of the cars added and their category, the vehicles excluded are: all armored and weaponized cars, all movie based cars and the 4 vehicles owned by the protagonists.
