To add grass planting: Unzip map, open map/map.i3d with Notepad++. Inside `<Files>` section, add `<File fileId="1633" filename="$data/foliage/grass/grass.xml"/>`. Then find `<FoliageMultiLayer densityMapId="639"` and inside it, add `<FoliageType name="grass" foliageXmlId="1633"/>`. Save. Grass fixed! 🙂
