So does this mean that if I edit the main BMP file for say, the default Cessna 172, and make the alpha channel a lot darker, it will make the plane's exterior a lot more shiny? Or even completely chrome? Or do I have to actually do something more in Gmax to make this work?
I was unsure whether to post this in this forum or the Repainting one, but I guess it's relevant in both.

Many thanks.
