Hi everyone,
I search on internet, even on this forum I saw some players like me but no clear answers.
The problem: some parts of some weapons doesn't want to be colored! even if I color the entire skin with the same color.
Example: I color the entire skin (2048*2048) of MP9 into red, the original skin of the loader remains... (take a look on the attached file)
the only answer I saw is "a manipulation with alpha channel" but I don't understand how it works.
I use Gimp and VTFEdit help 
(sorry for my broken English)
