The package includes 3 low poly cars that you can use in your mobile games or as test vehicles for your mobile game. The cars use only 1 diffuse texture (so 1 material) for all the components, and they also include 1 normal map. The wheels are separate meshes, but they use the same car texture.
The main diffuse texture of each car is in Photoshop format, so you can easily change it to whatever you want. All components of the car are mapped on different PSD layers so you can control everything if you want to create your own variations.
In addition to the PSD you also have 2 extra diffuse textures (TGA format) with different variations.
See the attached screenshots for more details regarding the poly count and texture resolutions.
