so i just started making custom skins and im actually pretty proud of myself so far. there is just one problem which is driving me insane at the moment and makes me want to throw my pc out of the window....
my gun is supposed to look kind of matt or at least not that shiny so i changed all colors to solid ones already. however: whenever i spin the weapon around in the preview in game there is so much light and reflection on it that the gun almost looks completely white/ grey at times...

can someone help me solve this issue please? im not really sure what to do right now :/

im using gimp by the way, cheers!
