Yeah that is the link, you can choose Vehicle Game that is also affected. Even before this it does not render correctly, it was mostly like nonexistent NightDay map + some corruption outside :D If you don't aware off you can try all three maps, by changing config with those i think: https://docs.unrealengine.com/latest/INT/Resources/Showcases/RealisticRendering/index.html#availablemaps But OK that is another bug ;)
