Yesss, somehow you' or the program your using applied an APLHA Channel to the entire aircraft body
I've ran into this before with downloads ,,,,
all chrome or too much reflection on entire body,,, looks like utter crap
After many hours of experimenting - using the DXT program,,,, I learned how to use the ALPHA,,,,,, menu at the top
you'll need to go experiment yourself,,,, and tinker around with with it and get rid of the ALPHA Channel that somehow got applied,,, that shouldn't have, or you didn't check something.
Its late and I got to work tomorrow Monday.
or I'd dive into it further with you,,,,
go experiment with your DXT and the ALPHA menu at the top , and practice on the main aircraft texture folder
NOTE : make plenty of back up copies, you'll need them 1st !!!!!!!
get back to ya later see how you did.
