These are previews presets to use with Content Manager.
There are two presets:
1. Preview - zoom 1: Suitable for smaller cars like Abarth etc.
2. Preview - zoom 2: Suitable for larger cars like Prototypes.
The lighting and shadows set up to emphasize car shapes and details so they look more like the real cars and make the preview thumbnails more pleasing to the eyes.
How to install: Put both files in
C:\Users\yourname\AppData\Local\AcTools Content Manager\Presets\Custom Previews
and activate using Content Manager.
Please feel free to use these presets in any mods - just please don't forget to credit me :-D
