Welcome to the mod! Here are the installation instructions and more tips for a better game experience with this mod.

Installation: 

popgroups.ymt - mods/update/update.rpf/x64/levels/gta5

popcycle.dat - mods/update/update.rpf/common/data/levels/gta5

Tips for an improved experience:

- Download and install my updated spawn color packs
- Go to Documents/Rockstar Games/GTA V/settings.xml and find the lines <CityDensity value="1.000000" /> and <VehicleVarietyMultiplier value="1.000000" />. Increasing these will create denser streets
and provide better variation among the vehicles. I personally have mine at 2 for the density value and 20 for the multiplier value, however, it mostly depends on your system. Experiment and try
to find that sweet spot that suits your needs.
- If you encounter any vehicles disappearing as you get closer, install Simple Trainer. That will prevent Online vehicles from despawning in SP.
