I have tried this and followed the instructions provided but everytime in game, some vehicles do not show the extra lights and addons properly. The effects are present as in lighting but a lot is missing. According to the editor it says "QSF noticed that prototype xxxxxx..... is using prefab asset xxxxx.......which apparently does not exist" Some vehicles has this tied to it. I remember previous installations of this you had 2 prefab and content folders to overwrite, in this version you only have the em5/data/content folder.
