I’ve placed around the city’s periphery, highway entrances to Los Santos and rural roads an italian radar sign, there are about 14 of them scattered around.
First of all open OpenIV and go trough mods/x64f.rpf/levels/gta5/props/roadside/v_signs.rpf and drop the prop and the textures there
For ymap installation:
Be sure to have ymap installed correctly: Map Editor & Menyoo to YMap Converter
Go trough mods/update/x64/dlcpacks/custom_maps/dlc.rpf/x64/levels/gta5/_citye/maps/custom_maps.rpf and drop the xml file from ymap folder
For MapEditor installtion:
Also be sure to have Map Editor correctly installed
Just drop the XML file intro your Gta5 directory folder and when in game press the load map button and search for RadarIT file
Enjoy !
