so ive been modding my game with new cars and ive been also trimming off the useless stuff in dbmodelparts (attachments, damage1/0 and bodykit 6) to fit in more cars, and now when i play the game my gauges are black
You didn't really specify which game this was, but I'm assuming it's a game with customizable gauges like MW or UG2? If so, it's possible that you might have deleted something that was tied to the UI customization options (assuming they're in DBModelParts).
I apologize if this isn't helpful, as I'm very new to NFS modding myself, and have only been modding Carbon (which doesn't have customization for UI). So, I'm not entirely sure whether or not this is actually the issue...
