ever since the new update there is no texture in the 3 maps. its the title. in wcusa there is no tunnel, no bridges, no buildings but some. in jrl all of the roads are no texture and the buildings. in hirchoi race way nothing. just dirt.
Clear cache. Try using safe mode. If it occurs in safe mode then: verify integrity of files. If THAT doesn't fix, try doing a fresh install of game and try again.
I had this happen to me the other day after not playing the game for a while. Clearing cache fixed it for me. I have never had to do a clean install. They must have changed a bunch of image names for the vanilla maps, because now none of my map mods have textures. I use shared assets to save download size on big redundant stuff like textures, so this is a nightmare for me.
the install won't do anything if you don't also clear cache/delete the userfolder. you most likely wouldn't've had to reinstall the game
