Coming from THIS thread, i was curious an loaded the SLS SC into the DevMode. That's how it showed up there in the Showroom and also on track: To solve it, i had to do 5 things: I had to rename 3 meshes (important parts are bold): SLSAMG_BLACK_GLASS.GMT SLSAMG_HEADLIGHTS.GMT SLSAMG_REARLIGHTS.GMT and 2 Material Names: SLSAMG_BLACK SLSAMG_EXTERNAL Maybe not all of these changes are necessary, but after changing these, the Car showed up with all Parts, in the Showroom and on Track. And maybe that can be fixed with the next Update?
