I don't mind if it's a dupe, as you said, better than sorry. I hope to see more as you are the only one who actually give something I really want for so long since I wasted my money on GOM cars saying his cars were lore friendly and they weren't ( The IRL custom cars back in the days ) so I'm happy that you provided the community with such good content and it's actually lore friendly ! Keep up the good works, take care !
Yes, decrypters are payed, I don't have access to such tools, the escrow is locking the files regardless the type format. If you don't have a decrypter there is no chance you can unlock the models.
Removing the fxap file won't unlock the car. The model itself is encrypted through escrow system, you will need a fxap decrypter for that and then you can unlock the car with xml and import it in blender etc.
