I decided to try dabbing my feet in popcycle and popgroups, as I have a ton of addon police cars and would like them to spawn in traffic.
I found the popgroups.ymt in mods/update/update/x64/levels/gta5 and have added some vehicles (a few to start, make sure it works). However, I am unable to find any file that has sheriff and sheriff2. From a 6 year or so post on LSPDFR I was able to find out I need to look for RURAL something in the data file itself. The problem is, none of the popgroups I can find have it. Does anyone know where sheriff and sheriff are located so I can add more ambient sheriff traffic?
