First of all, the NFS-TexEd program allows you to open the game archive "LIVERYTEXTURES" with liveries (AI-rivals), and view them. And the most important thing is that you can export Need for Speed ProStreet liveries without losing quality, and also import your edited ones into the game (replacing existing ones).
It is important that you will see the modified liveries of AI-rivals in any case, under favorable circumstances. And for yourself, you need to open an additional option in the "Vinyls" section, called "Special". And even then, you will not see the changes right away! You need to somehow reset the game cache, or other possible manipulations (maybe over time).
The path along which you need to search for the "Need for Speed™ ProStreet/CARS/VINYLS" archive "LIVERYTEXTURES" of ready-made liveries.
Quick guide:
1. Run the program as administrator.
2. Click "Archive", then "Open", and find "LIVERYTEXTURES" (or other files of interest).
3. You can simply view it, or you can import your livery (or export it from the game).
4. Be sure to save any changes "Save" if necessary.
The NFS-TexEd utility for NFS ProStreet is the same "BinTex", which in its case does not show a picture. In addition, all sorts of other textures can be imported and exported (the main thing is to know where to look).
