Problem whit alpha channel

[Trosemafo]

I have a problem that I think is due to the alpha channel. I edit the texture of any car and put the original alpha channel on it, but when I open the game, the car texture has a lot of shine (in Flatout 2 I fix this by adding the original alpha channel). I don't know if it's because of the texture, but the car is too bright like I didn't add an alpha channel.

From my experience if you edit the original stock texture the alpha channel does not change and does not need to be replaced. I use Photoshop CS3. Do you have a texture I could look at?
