This mod replaces vegetation textures. You will recognize native birches in the trees. It's nice to see something like this in Liberty. They look very good. Somewhere red trees resemble the warm beginning of autumn, and somewhere a hot, blooming summer. For more realistic vegetation, use the “Smooth Trees Mod 1.0” mod from DexX. The textures look good both day and night.
Installation:
Open the GTA IV installation folder (X:/Program Files/Rockstar Games/Grand Theft Auto IV/pc/data/maps/props/) (don't do the same for Steam, Google is your friend)
Copy VegatIV to the "vegetation" folder and replace the old files.
