Advanced FBI Variations

As I understand it, I also need to edit the file (ModelVariations_Peds.ini), but what exactly do I need to specify?

[286]
LosSantos=286,793,794,795,796
LasVenturas=286,793,794,795,796

Right?

You also try this: Name the file (for example fbi_add.ide) in this file indicate the necessary parameters. Inside the folder with the files (txd, dff) create a folder “data” and “maps” (inside the data folder). Place the file fbi_add.ide in the maps folder
In the "data" folder, create a file gta.dat.txt and specify a link to the file fbi_add.ide (example IDE DATAMAPSfbi_add.IDE). Haven't tested it, but it should work. In this case we edit the standard peds.ide file.
