I finally discovered how to rip NFS World cars without losing the glasses and badges! This problem haunted me since I started on NFSW ripping. Prepare to see a lot of NFSW releases now! I have 2 screenshots to make the comparison:
Up here it's the Lamborghini Aventador LP700-4 The Beast after I find out how to make the proper ripping.
And here I have the Audi A1 Clubsport Quattro Speed Edition before finding out what's the problem.
